Presentation
A young female patient came from the gynecologist outpatient clinic. On the TVUS, they found, in the midline, a cystic mass. The patient had lower abdominal discomfort half a year after stopping oral contraceptives.
Patient Data
The right ovary is 27 x 33 x 30 mm in size; there is a maximum diameter of 16 mm thin-walled fluid containing follicle, with a few similar smaller ones.
The left ovary is 32 x 23 x 26 mm in size, in it a maximum diameter of 9 mm; also, a thin-walled fluid containing follicles are seen.
Behind the body of the uterus, in the midline, is an approximately 31 x 34 x 24 mm in size mass is seen with sharp contour. A few maximum diameters of 7 mm fluid-containing follicles are visible on the periphery on every study phase with a low central sign intensity.
On the postcontrast studies, only a partial peripheral enhancing is seen. This mass is close to the rectum's left side, but it can be safely differentiated from it. The rectum is a little bit displaced to the right side and compressed a little bit.
In the pouch of Douglas, minimal, maximum 10 mm deep free fluid is visible.
Case Discussion
A young female with lower abdominal discomfort after stopping oral contraceptive came from the outpatient clinic with ultrasound findings of a mass in the pelvis's midline. The ultrasound morphology was not typical. On the MRI, it is also similar in morphology to normal ovarian tissue. It could be a supernumerary ovary, according to the radiology finding. Still, the patient went on laparoscopic surgery, and they removed the mass, and according to the histology, it was a cystadenofibroma serosum.
