Managing ovarian masses during pregnancy is a critical issue while they can complicate pregnancy either by their size or nature. In this report, the management of a large ovarian mass as an interesting incidental finding on ultrasonography will be discussed. In present report, a 33-year-old woman referred with a dull abdominal pain in 32th weeks of gestation. Her sonographic evaluation revealed a large solid-cystic mass of right ovary about 20 centimeter length. The patient underwent a laparotomy under regional anesthesia. There was a large mass originating from right ovary without any adhesion to surrounding tissues and a normal pregnant uterine in third trimester. The right ovary complicated by a multilocular solid-cystic mass was removed and the pathology report showed papillary serous cystadenoma of ovary. In outpatient management, the mother passed a normal pregnancy. In conclusion; physiological changes during pregnancy may complicate manifestations of diseases in pregnancy. Under diagnosis of any abdominal compliant may lead to life-threatening situations such as overgrowth or torsion of ovarian masses. Gentle action with minimal manipulation of pregnant uterus could prevent adverse outcomes.
