Supernumerary Ovary Characterized byCystic Changes in the Omentum: A Rare Pathology

Supernumerary ovary is a rarest gynecologic condition in children. The presence of cystic changes within the supernumerary ovary\ris extremely rare. We report a case of neonate with supernumerary ovary. The patient was 3-month-old girl with a right-side cyst diagnosed by\ra prenatal ultrasonographic evaluation. Ultrasonography performed right after birth, and a magnetic resonance imaging examination had revealed\rthat the abdominal cystic mass contained patchy semisolid components within a hemorrhagic or mucinous fluid. Laparotomy revealed a cystic\rmass which has no connection with the normal reproductive organs. Two normal ovaries were identified in the abdominal cavity. After excision,\rhistopathologic study revealed that cystic mass was supernumerary ovary on the omentum. The baby had no postoperative complications. Prenatal\rdifferential diagnosis of abdominal cystic masses in infants with supernumerary ovary will be useful to keep in mind.
