Giant Ovarian Cyst in a Term Pregnancy Simulating a Massive Ascites: A Case Report

The diagnosis of ovarian mass during pregnancy may be missed if early ultrasonographic assessments of pregnancy are not done, resulting in late detection and management. Hence, this case report is aimed at underscoring the possibility of misdiagnosis of a giant ovarian mass for massive ascites in pregnancy. We present the case of a 35-year-old unbooked multigravida woman who was referred to our centre on account of polyhydramnios in labour, misdiagnosed as a massive ascites on admission. The incidental intraoperative diagnosis of a right giant ovarian cyst resulted in the right salpingo-oophorectomy of a huge cyst with the histological diagnosis of a benign ovarian serous cystadenoma. Huge cystic ovarian tumours coexisting with a normal pregnancy may simulate massive ascites resulting in a misleading diagnosis as reported in this case study. We report this case to awaken the suspicion index of a giant ovarian cyst in any patient presenting with massive ascites in pregnancy.
