Can you have a lipoma on your ovary?
Abstract. Background: Ovarian lipomas are a rare entity, with most being described as part of a teratomatous origin. This is a case report of a lipoma of an ovary not associated with a teratoma or an hyperandrogenic state.
How is ovarian torsion definitively diagnosed?
Ultrasound is the diagnostic modality of choice for detecting torsion. The absence of blood flow within the ovary on Doppler exam is a highly specific finding but the presence of Doppler flow does not exclude the diagnosis of torsion.
What is the gold standard for ovarian torsion?
diagnostic imaging with either ultrasound (US) or computed tomography (CT) [4,6,8]. Pelvic US has traditionally been considered the optimal imaging modality for diagnosing ovarian torsion due to its ability to directly evaluate both ovarian anatomy and perfusion, as well as its low cost and lack of radiation.
How do you investigate ovarian torsion?
Diagnostic investigations
- CBC.
- pregnancy test.
- transvaginal ultrasound with Doppler flow.
- abdominal ultrasound.
- genetic probe or cervical culture.
- urinalysis.
- surgical visualization.
What does a lipoma look like?
Lipomas often form in the fatty tissue under the skin. These are also the most noticeable ones, as they look and feel like soft, dome-shaped lumps under the skin. They vary in size from pea-sized to several centimetres in diameter.
What does ovarian torsion look like on ultrasound?
Ovarian torsion ultrasound findings may vary, but a unilateral enlarged (>4 cm) edematous ovary with peripheral cysts and free pelvic fluid is pathognomonic. The peripherally displaced follicles are due to the engorged central ovarian parenchyma.
Can you see ovarian torsion on ultrasound?
Ovarian torsion is usually associated with a cyst or tumor, which is typically benign; the most common is mature cystic teratoma. Ultrasonography (US) is the primary imaging modality for evaluation of ovarian torsion.
When should you suspect ovarian torsion?
The most common clinical symptom of torsion is sudden-onset abdominal pain that is intermittent, nonradiating, and associated with nausea and vomiting. If ovarian torsion is suspected, timely intervention with diagnostic laparoscopy is indicated to preserve ovarian function and future fertility.
Can ultrasound differentiate between lipoma and liposarcoma?
A well-differentiated, peripheral liposarcoma is usually hyperechoic and may be indistinguishable from a lipoma; however, Doppler ultrasonography studies reveal that a liposarcoma is more vascular than a lipoma.
Can an ultrasound detect liposarcoma?
Liposarcoma can be seen on ultrasound. One of the diagnostic imaging tests used to diagnose liposarcoma includes ultrasound. In some cases, ultrasound can be used to help differentiate the type of liposarcoma based on the characteristics found on the sonogram.
What does a lipoma look like on an ultrasound?
Traditionally it has been taught that the sonographic appearance of a simple lipoma is consistent with a hyperechoic mass with no posterior acoustic enhancement (4). These soft-tissue masses are lower in reflectivity than muscle but more reflective than adjacent subcutaneous fat.
How do you diagnose ovarian torsion with ultrasound?
The diagnosis of ovarian torsion is usually made by the clinical examination findings and diagnostic imaging modalities, in which ultrasound examination with color Doppler analysis takes great part. However, use of color Doppler imaging has some controversies as the presence of vascular flow does not rule out torsion [18].
What is pathognomonic ovarian torsion?
good at ruling out ovarian torsion if a normal ovary/adnexa is seen on ultrasound. the twisted ovarian pedicle is pathognomonic for ovarian torsion if demonstrated 11. torsion appears as a complex adnexal lesion representing enlarged ovary (>4.0 cm 11) distended pedicle.
What are the USCUS features of ovarian torsion?
US features of ovarian torsion include a unilateral enlarged ovary, uniform peripheral cystic structures, a coexistent mass within the affected ovary, free pelvic fluid, lack of arterial or venous flow, and a twisted vascular pedicle.
What does an enlarged ovary look like on an ultrasound?
In our case, ultrasound showed an enlarged ovary, measuring over 4 cm, with a heterogeneously architecture and a moderate amount of intraperitoneal free fluid. Colour Doppler ultrasound demonstrated blood flow of the left ovary and adnexal mass, and thus resulting in a false negative diagnostic of ovarian torsion.
