Paraovarian Cyst Mimicking Mesenteric Cyst : A Case Report

Paraovarian cysts are cystic lesions occurring adjacent to the ovaries in women of reproductive age group. We present a case of a 30 year old female presenting with a lump in the abdomen. She was initially suspected on clinical and radiological examination to have a mesenteric cyst. However, exploratory laparotomy revealed it to be a paraovarian cyst. Histopathology confirmed it to be serous cystadenoma. The relevant discussion focuses on the clinical features, diagnosis, treatment and outcome of patients with paraovarian cysts. *Professor; **Asso.

Introduct ion P cysts, constituting 10-20% of all adnexal masses, arise from the broad ligament, usually from mesothelial and paramesonephric elements or, rarely, from mesonephric remnants.1 Paraovarian cysts occur over a wide age range, most commonly in the third and fourth decades.2 Most of them are asymptomatic but rarely they become large in size and cause clinical symptoms such as increase abdominal girth, lower abdominal pain.3 They are rarely considered in the differential diagnosis of lumps that clinically resemble mesenteric/omental cysts. We present the case of a 30 year old woman with a left sided paraovarian cyst that presented as a lump in abdomen initially suspected as a mesenteric cyst.
