Ovarian mucinous cystadenoma

Case contributed by Dr Jini P Abraham


Presented with mass per abdomen and pelvis for 1 month.

Patient Data

Age: 25 years
Gender: Female

Evidence of a predominantly T2 hyperintense cystic lesion with multiple internal septations and loculations within noted in the midline superior to urinary bladder. Few areas of T1 hyperintensity noted which are not suppressed on T1 FATSAT images, suggesting hemorrhage/protein within. Post contrast study shows enhancement of the septae.

Right ovary appears normal. Left ovary not visualized separately. Uterus is pushed towards the left side.

Impression - left ovarian cystadenoma (Mucinous variety).

The patient underwent laparotomy and left salpingo-oophorectomy.


Gross features - Outer surface: Smooth, congested blood vessels. Cut surface: Multiloculated cyst, draining mucinous fluid, no solid areas identified.

Microscopy - Sections show cyst wall lined by tall columnar mucinous epithelium with underlying fibro collagenous stroma, showing endocervical like glands lined by mucinous epithelium exhibiting minimal nuclear stratification and varying sized blood vessels.

Impression - Left ovarian mass: Benign mucinous cystadenoma.

Case Discussion

This is a pathologically proven case of mucinous cystadenoma. Mucinous cystadenoma are benign tumors with excellent prognosis. Commonly occurs in the age group of 30-50 years. These lesions are often large, multiloculated cyst, having honeycomb-like locules.
