Ovarian torsion is a rare but potentially life-threatening medical condition in which an ovary twists around the ligaments that hold it in place, disrupting its blood supply and causing severe pain. This condition requires immediate medical attention and timely treatment to prevent damage to the ovary and ensure the patient’s wellbeing.
To rule out ovarian torsion, healthcare professionals generally rely on imaging tests, clinical examinations, and patient history.
Firstly, imaging tests like ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) may be used to diagnose the condition. Ultrasound is usually the first imaging test used to detect ovarian torsion, as it can quickly identify any structural abnormalities and changes in blood flow to the ovary.
CT and MRI can also be used to provide more detailed images of the pelvis and help distinguish between ovarian torsion and other similar conditions.
Secondly, clinical examinations, which involve physical examination and laboratory tests, can also help rule out ovarian torsion. During a physical examination, a healthcare professional will check for any signs or symptoms, including abdominal pain, nausea, vomiting, or fever. They may also conduct a pelvic exam to assess the size, shape, and position of the ovaries.
Lastly, patient history plays a critical role in ruling out ovarian torsion. It is essential to consider any factors or underlying conditions that may increase the risk of torsion, such as previous surgeries, ovarian cysts, or pregnancy. Additionally, patients’ symptoms, including the severity of the pain, duration, and onset, can help healthcare professionals make a proper diagnosis.
Ruling out ovarian torsion involves a comprehensive approach, including imaging tests, clinical examinations, and patient history. These measures enable healthcare professionals to diagnose the condition accurately, rule out other similar conditions, and ensure timely and appropriate treatment to minimize risks and complications.

What is the way to diagnose ovarian torsion?
Ovarian torsion is a medical emergency that can cause severe pelvic pain and can even result in the loss of the affected ovary. Therefore, prompt diagnosis and treatment are crucial for the patient’s well-being. To diagnose ovarian torsion, healthcare professionals usually use a combination of physical examination, imaging tests, and laboratory tests.
The first step in diagnosing ovarian torsion involves a thorough physical examination, where the healthcare professional will look for signs and symptoms of the condition. Patients with ovarian torsion typically report sudden and severe pelvic pain, which may be accompanied by nausea, vomiting, and fever.
During the physical examination, the healthcare professional may palpate the abdomen and pelvis to identify any tenderness or swelling. They may also perform a pelvic exam to check for any abnormal findings, such as a mass or enlarged ovary.
Imaging tests are usually recommended to confirm the diagnosis of ovarian torsion. An ultrasound scan is the preferred imaging test for this, as it can help identify any changes in the appearance and blood flow of the ovaries. If the affected ovary has twisted, the blood flow to it will be reduced or cut off completely.
An ultrasound scan can also help rule out other conditions that may present with similar symptoms; for example, it can detect the presence of ovarian cysts, which can also cause pelvic pain.
In certain cases, additional imaging tests may be necessary to confirm the diagnosis or rule out other conditions. For instance, a computed tomography (CT) scan or magnetic resonance imaging (MRI) may be recommended if the ultrasound scan is inconclusive or if there are other underlying conditions that need to be ruled out.
Laboratory tests may also be performed to aide in the diagnosis of ovarian torsion. A complete blood count (CBC) is usually performed to check for signs of infection, such as an elevated white blood cell count. Additionally, measuring the levels of certain hormones such as estrogen, progesterone, and luteinizing hormone can provide useful insights into the functioning of the ovaries.
To conclude, the diagnosis of ovarian torsion involves a combination of physical examination, imaging, and laboratory tests. Timely diagnosis is crucial, and patients should seek medical attention immediately if they experience sudden and severe pelvic pain. Early diagnosis and appropriate treatment can increase the chances of a successful outcome and improve the patient’s quality of life.
Does ovarian torsion show on ultrasound?
Ovarian torsion is a medical condition that occurs when the ovary twists around the tissues that support it, leading to a reduction in blood flow to the ovary. This can cause severe pain and discomfort in the lower abdomen, nausea, vomiting, and fever. Ovarian torsion can be a medical emergency and requires immediate medical attention to prevent permanent damage to the ovary.
Ultrasound is a non-invasive imaging technique that uses high-frequency sound waves to create images of the body’s internal structures. It is a valuable tool in the diagnosis of ovarian torsion. Ultrasound examinations can be performed either transabdominally or transvaginally, with the latter being preferred due to the proximity of the ovaries to the vaginal walls.
However, the diagnosis of ovarian torsion can be challenging, as the symptoms associated with it can also mimic other conditions such as ovarian cysts, endometriosis, or pelvic inflammatory disease. Therefore, it is essential to perform a detailed ultrasound examination to detect any abnormalities that may suggest ovarian torsion.
Ultrasound imaging can detect a variety of findings that may indicate ovarian torsion. For example, the ovary may appear enlarged or have an irregular shape, and the presence of fluid in the pelvis may suggest that the ovary has twisted around itself, impeding blood flow. In some cases, a whirlpool sign, a pattern of twisted blood vessels around the ovary may also be observed on ultrasound.
However, it is important to note that not all cases of ovarian torsion may show up on an ultrasound. In some cases, the ovary may appear normal despite the torsion, or the imaging may not show any signs of ovarian torsion.
Ultrasound is a valuable tool in the diagnosis of ovarian torsion. It can detect various findings that may indicate ovarian torsion and help prevent permanent damage to the ovary. However, in some cases, the imaging may not show any signs of ovarian torsion, and other methods of diagnosis may be necessary.
Therefore, it is essential to seek immediate medical attention if you experience any symptoms or signs of ovarian torsion.
What imaging is for ovarian torsion?
Ovarian torsion refers to the twisting or flipping of an ovary around its axis, which can result in a restriction of its blood supply, leading to pain and potentially serious complications. The diagnosis of ovarian torsion requires a combination of clinical assessment and imaging studies, both of which are important for establishing the diagnosis as well as guiding the management of the condition.
The imaging modalities used in the diagnosis of ovarian torsion include ultrasound and computed tomography (CT) scan. Ultrasound represents the primary imaging modality of choice for the diagnosis of ovarian torsion due to its noninvasive nature, cost-effectiveness, and widely available technology, particularly in emergency and gynecologic settings.
Ultrasonography can identify an enlarged ovary and its characteristic features of twisting, including the presence of a whirlpool sign, which is visualized by observing the rotation of the suspended ovarian mass around its axis.
Other ultrasound findings suggestive of ovarian torsion include an absent or decreased blood flow signal within the ovary, which indicates ovarian ischemia, and the presence of a twisted vascular pedicle or a ‘corkscrew’ appearance of the vascular structures. Additionally, the use of doppler ultrasound can be quite informative as it can detect areas of decreased or absent blood flow and identify preserved perfusion of the uterus and contralateral ovary, which help exclude other causes of lower abdominal pain.
On the other hand, CT scan can be utilized when there is a suspicion for a ruptured ovarian cyst or when concurrent pathology, such as appendicitis or diverticulitis, is also a possibility. This imaging modality can also demonstrate the presence of an enlarged ovary, ovarian masses, or other pelvic pathology suggestive of acute ovarian torsion.
The imaging modalities of choice for the diagnosis of ovarian torsion include ultrasound and CT scan, with ultrasound being the primary imaging modality. A combination of clinical assessment and imaging studies is essential for a timely and accurate diagnosis of this condition, which can help prevent potentially serious complications.
Is ovarian torsion pain constant?
Ovarian torsion is a medical condition that occurs when the ovary twists around its ligaments resulting in cut-off blood flow to the ovary. This condition is commonly associated with moderate to severe pain which can sometimes mimic symptoms of other conditions such as appendicitis or kidney stones.
However, the extent of pain experienced may vary depending on the severity of the torsion.
In most cases, pain caused by ovarian torsion is sudden, sharp, and severe. It may develop suddenly and without any warning or it may come and go in waves. Some women describe the pain as a stabbing or throbbing sensation, while others experience a dull, achy pain or a feeling of pressure in the pelvic area.
The location of the pain can also vary depending on the position of the ovary and may be felt on one or both sides of the lower abdomen or pelvis, or radiate to the back or thighs.
Many women may experience constant pain with ovarian torsion while others may have intermittent pain that can come and go. In some cases, the pain may be mild or affect one’s daily activities only minimally. However, it is important to note that the level of pain does not necessarily correlate with the severity of the torsion, and it is possible for a woman with mild torsion to experience more pain than a woman with severe torsion.
Other symptoms commonly associated with ovarian torsion include nausea, vomiting, fever, and sweating. Women may also experience vaginal bleeding, irregular periods or missed periods, pain during intercourse, and swelling or tenderness in the affected area.
The level of pain experienced with ovarian torsion can vary from woman to woman and may be constant or intermittent. Women who experience sudden, severe pain in the pelvis or lower abdomen, accompanied by other symptoms, should seek medical attention promptly to rule out ovarian torsion as a potential cause.
Early diagnosis and treatment are essential to prevent severe damage to the ovary and improve outcomes for affected women.
What is the most common finding on ultrasound for ovarian torsion?
The most common finding on ultrasound for ovarian torsion is the absence or reduction of blood flow to the affected ovary. This decrease or absence of blood flow is typically seen on Doppler ultrasound as a lack of color Doppler signal or arterial flow within the ovary. Other common findings seen on ultrasound include an enlarged ovary due to engorgement with blood, an ovarian mass or cyst, or free fluid in the pelvis, which may be due to hemorrhage or necrosis of the affected ovary.
It is important to note that not all cases of ovarian torsion may present with the same ultrasound findings, as the severity and extent of damage to the ovary may vary. In some cases, ovarian torsion may be elusive on ultrasound and may require further imaging studies or surgical exploration to confirm the diagnosis.
the most common finding on ultrasound for ovarian torsion is reduced blood flow to the affected ovary, but other findings including an enlarged ovary, ovarian mass, and free fluid may also be present.
Does ultrasound rule torsion?
Ultrasound is a commonly used diagnostic imaging technique in many medical fields, including obstetrics and gynecology. When it comes to ruling out torsion, ultrasound can be a useful tool, but it is not always definitive.
Torsion refers to an abnormal twisting of an organ, usually the ovary or testicle, that can cause significant pain and damage to the affected tissue. Ultrasound can help in diagnosing torsion by providing images of the affected organ and surrounding tissues. If torsion is suspected, ultrasound can identify changes in blood flow to the affected organ, which can be an indication of compromised blood supply due to twisting.
However, there are limitations to using ultrasound to diagnose torsion. For one, not all cases of torsion will result in changes in blood flow that can be detected on ultrasound. Additionally, other conditions, such as cysts or tumors, can also cause changes in blood flow and mimic torsion on ultrasound.
In some cases, a physician may need to rely on other diagnostic tests or even surgical exploration to definitively diagnose torsion. However, if ultrasound is performed by an experienced technician and interpreted by a skilled physician, it can be a reliable tool in ruling out torsion and guiding further diagnostic and treatment measures.
While ultrasound can be a useful tool in diagnosing torsion, it is not always definitive. Physicians must consider other factors, including the patient’s symptoms, medical history, and results from other diagnostic tests, when making a diagnosis. In cases where ultrasound suggests torsion, it is important to follow up with additional testing and intervention as necessary to prevent further complications.
Can ovarian torsion resolve itself?
Ovarian torsion is a medical condition where the ovary twists around its ligamentous supports, causing a decrease in blood flow to the ovary and, in severe cases, tissue death. The symptoms of ovarian torsion include sudden and severe lower abdominal pain, nausea, vomiting, and fever.
In some cases, ovarian torsion can resolve itself without intervention. However, this is extremely rare and usually occurs when the torsion is partial and the ovary returns to its original position before cutting off blood flow. This can be difficult to diagnose and requires close monitoring and follow-up appointments with a healthcare provider.
In most cases of ovarian torsion, medical intervention is required to prevent further complications. Treatment options for ovarian torsion may include surgical intervention, such as laparoscopy or laparotomy, to untwist the ovary and restore proper blood flow. In severe cases, removal of the affected ovary may be necessary to prevent tissue death or the development of an abscess.
Delaying treatment for ovarian torsion can lead to serious complications, including infertility, sepsis, and the development of ovarian or fallopian tube cancer. Therefore, prompt medical attention is necessary if you suspect ovarian torsion.
While some rare cases of ovarian torsion may resolve themselves, most require medical intervention to prevent further complications, and prompt attention is necessary for a positive outcome. It is important to contact a healthcare provider immediately if you experience sudden and severe lower abdominal pain or suspect ovarian torsion, as early intervention can lead to better outcomes.
Does ovarian torsion cause leukocytosis?
Ovarian torsion is a serious condition that occurs when the blood flow to the ovary is disrupted due to the twisting of the ovarian pedicle. This can result in ovarian ischemia, which is a condition where the blood flow to the ovary is decreased or completely cut off. One potential consequence of ovarian torsion is leukocytosis.
Leukocytosis is a medical condition characterized by an increase in the number of white blood cells in the blood.
The reason why ovarian torsion can cause leukocytosis is because of the body’s response to injury or infection. When the ovary is twisted, it becomes ischemic or dead, and there is a possibility of tissue damage or necrosis. This damage leads to an inflammatory response, which is part of the body’s natural healing process that helps to fight off infections and repair tissue damage.
White blood cells are a critical component of the inflammatory response, and they help to identify and remove pathogens and dead cells from the body. As a result, the number of white blood cells in the blood can increase, resulting in leukocytosis.
However, leukocytosis is not always a definitive sign of ovarian torsion. It is important to note that leukocytosis is a nonspecific sign, meaning that it can occur in response to a variety of conditions, including infections, inflammation, autoimmune diseases, cancers, and trauma. Therefore, the presence of leukocytosis alone is not enough to diagnose ovarian torsion.
Other symptoms and physical examination findings, such as abdominal pain, nausea, vomiting, and a palpable adnexal mass, may also be present.
Ovarian torsion can cause leukocytosis as part of an inflammatory response to tissue damage or necrosis. However, leukocytosis alone is not always indicative of ovarian torsion and should be interpreted in conjunction with other clinical findings. Prompt recognition and treatment of ovarian torsion are crucial to prevent further tissue damage and potential complications, including ovarian failure or even death.
What every radiologist should know about adnexal torsion?
Adnexal torsion is a medical emergency that occurs when the ovary or fallopian tube twists on its own blood supply, leading to ischemia and potential necrosis. As a radiologist, understanding the key clinical and radiographic features of adnexal torsion is essential for accurate diagnosis and prompt treatment, which can significantly impact patient outcomes.
Firstly, it is important to be aware of the typical patient demographics and clinical presentation of adnexal torsion. This condition often affects women of reproductive age and is more common in those with ovarian cysts or masses. Typical symptoms include sudden onset lower abdominal pain, nausea, vomiting, and fever, sometimes accompanied by vaginal bleeding.
These symptoms may mimic other gynecological conditions such as pelvic inflammatory disease or ovarian rupture, so a careful history and physical examination are critical.
In terms of imaging, ultrasound is the first-line modality for assessing adnexal torsion. On ultrasound, an enlarged ovary or adnexal mass with a twisted pedicle will show decreased or absent blood flow, typically confirmed with Doppler interrogation. Furthermore, the surrounding tissues may exhibit inflammatory changes, such as free fluid, thickened fallopian tubes, or complex adnexal masses.
Multiplanar imaging is needed to accurately assess torsion, and the radiologist should specifically look for whirlpool sign, a typical sonographic finding that can confirm a twisted vascular pedicle.
Computed tomography (CT) or magnetic resonance imaging (MRI) may be indicated, especially if the diagnosis is uncertain, or if an adnexal mass or cyst is seen. CT may show a unilateral adnexal mass with surrounding inflammatory changes and thickening of the ipsilateral fallopian tube, as well as a twisted vascular pedicle.
MRI can provide superior soft tissue contrast resolution, and allows better evaluation of vascular and anatomical structures, especially in a complex adnexal mass.
Early diagnosis and prompt treatment are crucial in adnexal torsion. Treatment options may include surgery, with either detorsion and preservation of the ovary and tube, or oophorectomy or salpingectomy if the torsion caused necrosis or rupture. Radiologists should be alert to the possibility of complications such as peritonitis, sepsis, or abscess formation, and work closely with the clinical team to ensure effective management and follow-up care.
Adnexal torsion is a challenging emergency condition that requires a multidisciplinary approach and prompt diagnosis and intervention. As radiologists, we play a critical role in recognizing the key clinical and imaging features of adnexal torsion, and providing accurate and timely diagnostic information to guide patient care.
How sensitive is a CT scan for ovarian torsion?
CT scans are one of the imaging techniques that can be used to diagnose ovarian torsion. Ovarian torsion is a gynecological emergency that arises when the ovary rotates around its axis, causing its blood vessels to get twisted and compromising its blood flow. This condition can lead to serious complications such as ovarian necrosis, sepsis, and even death if not diagnosed and treated promptly.
While CT scans can be useful in detecting ovarian torsion, their sensitivity may vary depending on several factors. One of the factors that affect the sensitivity of CT scans for ovarian torsion is the timing of the scan. In the early stages of torsion, the blood flow to the ovary may still be present, and hence, the CT scan may not show any concrete evidence of ovarian torsion.
Conversely, if the ovarian torsion is advanced, the CT scan may show a lack of blood supply and signs of ovarian necrosis, which can confirm the diagnosis.
Another factor that may influence the sensitivity of CT scans is the size of the ovary. Smaller ovaries may be more challenging to visualize on a CT scan, and may not show definite evidence of torsion compared to larger ovaries. Additionally, the level of radiologist expertise and the quality of the CT scan may also impact the sensitivity of the examination.
In general, the sensitivity of CT scans for ovarian torsion is estimated to be around 70-80%. This means that in 20-30% of cases, the CT scan may not show specific signs of torsion, and therefore, a comprehensive evaluation that includes clinical examination, medical history, and other imaging modalities such as ultrasound, may be necessary to diagnose ovarian torsion definitively.
While CT scans can be useful in identifying ovarian torsion, their sensitivity may vary depending on the timing of the scan, the size of the ovary, and other factors. Therefore, a multi-modal approach that incorporates clinical assessment and complementary imaging studies may be necessary to accurately diagnose ovarian torsion and prevent serious complications.
Can a CT scan show problems with ovaries?
Yes, a CT scan can show problems with ovaries. A CT scan, also known as a computed tomography scan, is a medical imaging technique that uses X-rays and computer technology to produce detailed images of various parts of the body. CT scans are commonly used to diagnose and evaluate a variety of medical conditions, including problems with the ovaries.
There are several types of ovarian problems that can be detected by a CT scan. These include ovarian cysts, tumors, and other growths. Ovarian cysts are fluid-filled sacs that can form on or within the ovaries. They are often benign and may not cause any symptoms, but in some cases they can become large, cause pain or discomfort, and require treatment.
A CT scan can help identify the size, location, and characteristics of ovarian cysts, which can guide treatment decisions.
Ovarian tumors and other growths can also be detected by a CT scan. These can include both benign and malignant tumors, as well as other types of growths such as endometriomas (cysts formed by endometrial tissue located outside the uterus). A CT scan can help determine the size, location, and characteristics of these growths, as well as the degree of involvement of other adjacent structures.
In addition to helping diagnose and evaluate ovarian problems, CT scans can also be used to guide treatment. For example, if a woman requires surgery to remove an ovarian cyst or tumor, a CT scan can help guide the surgeon in locating the growth and determining the best approach for removing it. CT scans may also be used to monitor the growth and progression of ovarian tumors over time, which can help guide treatment decisions and improve outcomes.
A CT scan can be an important diagnostic tool in identifying and evaluating ovarian problems such as cysts, tumors, and other growths. It can also be used to guide treatment decisions and monitor the progress of these conditions over time. If you are experiencing symptoms of ovarian problems, such as pelvic pain, bloating, or abnormal bleeding, talk to your doctor about whether a CT scan may be appropriate for you.
How sensitive is CT for appendicitis?
Computed tomography (CT) is widely used for the diagnosis of acute appendicitis, and its sensitivity has been reported to be between 89-98%. CT is a non-invasive imaging modality that allows for high-resolution imaging of the abdominal region.
CT has several advantages over other imaging modalities for the diagnosis of appendicitis. It can identify not only the appendix but also other potential sources of abdominal pain. CT has a high sensitivity and specificity in detecting appendicitis, which makes it useful in the emergency setting for detecting acute appendicitis.
It can be performed rapidly, and patients can be sent immediately for surgical intervention if necessary.
However, CT is not a perfect tool and may miss some cases of appendicitis. False-negatives can occur due to the presence of retrocecal appendicitis, a long appendix, or atypical presentation of the disease. Additionally, CT has the risk of radiation exposure to the patient, which needs to be considered, especially in young patients or pregnant women.
Despite these limitations, CT remains one of the most sensitive imaging modalities for diagnosing appendicitis. It can quickly provide high-quality images and help avoid unnecessary surgeries or delay in diagnosis. Therefore, CT is a valuable diagnostic tool for the assessment of appendicitis and other abdominal emergencies in both inpatient and emergency settings.
Medical professionals should understand the sensitivity and limitations of CT while using it as a diagnostic tool for appendicitis to provide accurate and timely diagnosis to the patients.
