Ovarian cysts are common incidental findings in term infants and, if unusually large, may result in dystocia, torsion, or rupture. We report the case in which serial sonographic examination revealed changing pattern of cystic ovarian mass from hypoechogenic to well defined multiseptated echogenic during pregnancy. Postnatal T2-weighted MR images revealed a multilocular with high signal density. After delivery a laparotomy was performed, and a twisted ovary measuring 6.7x5x4.5 cm was removed. Ovarian torsion was left-sided and had been almost autoamputated. The resected specimens were nontense, thin walled cysts, filled with hemorrhage like fluid. Histological examination demonstrated the presence of lymphangioma with widespread hemorrhage and necrosis. The neonate did well after the procedure.
