Abstract

The ectopic ovary is a rarely reported gynecologic entity. A variety of synonymous terms have been used to describe this condition, such as supernumerary ovary, accessory ovary, and ovarian implant syndrome. The etiology of ectopic ovary is poorly understood. The ectopic ovaries may occur in two ways. First, in the embryonic theories, they are believed to result from abnormal separation of a small portion of the developing and migrating ovarian primordium. Second, the accessory ovary can occur from acquired conditions such as inflammation and operations. In this report, we describe a case of the ectopic ovary with a mature cystic teratoma autoamputated into the cul-de-sac and subsequently diagnosed by laparoscopy.

Figure

• 

  Fig. 1 Transvaginal ultrasonogram. In Douglas pouch, a welldefined 5×4 cm sized cystic mass was noted. The cyst showed a smooth, regular outline with inhomogeneous internal echoes.

• 

  Fig. 2 T2 weighted magnetic resonance imaging (A) and fat suppression magnetic resonance imaging (B) in the transverse view of the pelvis showing left ectopic ovary (arrow) and normal right ovary (arrow head).

• 

  Fig. 3 Laparoscopic view of the pelvis. The mass was located in the Douglas pouch and not connected with the uterus or bilateral adnexa. The mass was adhered to pelvic wall with fine membranous tissue (A, B). Small sized left ovary was noted (C). Normal sized right ovary was noted (D).

• 

  Fig. 4 Photomicrography showed normal ovarian tissue (corpus luteum, arrow) and teratoma component (hair root sheath, etc) in the tumor. H&E stain, (A) ×20, (B) ×40.
