large ovarian mucinous cystadenoma in pregnancy: a case report

ABSTRACT

We report a case of large rare ovarian mucinous cystadenoma complicating pregnancy. Mucinous cystadenomas tend to be hormonally responsive during pregnancy and reach huge sizes. A 31-year-old woman gravida one, para zero, was found to have a right sided ovarian cyst at her first scan on seven weeks gestation measuring 12.1 x 7.8 cm. Serial scans throughout pregnancy showed an increase in the size of the cyst. The last scan done prior to elective cesarean showed a large complicated right ovarian cyst with multiple septation measuring 20.5x13.8x16cm extending to lower border of liver. Emergency cesarean section was undertaken at 38 weeks gestation due to fetal distress. After delivery of the baby, right salpingo- oophorectomy was performed. Histopathologically, a multi loculated benign mucinous cystadenoma was found. This case is fifth reported case of large overiancystadenoma complicating pregnancy in the literature. All ovarian cysts during pregnancy should be followed up by ultrasonography due to the possibility of adverse effects of the cysts on pregnancy
