Incidental Finding of an Accessory Ovary at Laparoscopic Surgery

An accessory ovary is one of the rare gynecologic abnormalities of the female genital tract. The etiology of accessory ovary has been reported to be acquired origin, such as postsurgical or postinflammatory implants, and true embryologic origin. However, as in the present case with unremarkable medical history and no urogenital abnormalities, there are accessory ovaries that cannot be explained by these etiologies. In such cases, the etiology of accessory ovary might possibly be torsion of functional ovarian cyst during the fetal period or asymptomatic torsion of the functional ovarian cyst at some time after birth.
