Two dermoid cysts developing in an accessory ovary and an eutopic ovary

Abstract

Accessory ovary is a rare gynecologic condition, and tumors arising in accessory ovaries are extremely rare. Accessory ovary may result from separation of migrating ovaries during embryogenesis and injuries such as inflammation and operation on normal ovary. Congenital malformations, most frequently malformations of the genitourinary organ, are seen in connection with the accessory ovary. We experienced the first case of two dermoid cysts developing in an accessory ovary located in the left infundibulopelvic ligament and another in the eutopic ovary at the same side concurrently. Here, we present this extremely rare case with a review of the literature.

Post-contrast helical CT scan shows a cystic mass with fat attenuation (short arrow). Another small, fatty mass with foci of calcification is noted at the left posterior aspect of this mass (long arrow). Normal appearing right ovary is noted (arrow heads).
