Gigantic Parovarian Cyst: A Rare Case Report

Giant parovarian cysts are rarely seen in adolescents. The cysts predominantly arise from mesothelium covering the peritoneum, usually in the broad ligament but sometimes may be seen between ovaries and ipsilateral fallopian tubes. Parovarian cysts constitute 10 to 33% of adnexal masses and are usually seen in the 3rd and 4th decades of life. These cysts may vary from small lesions to larger ones. Small cyst may remain undiagnosed but larger cyst usually presents with conditions due to pressure effect or swelling. Patients presenting with large paraovarian cyst need surgical treatment and the tumour can be removed by laparotomy. If the cyst can be separated from ovary and fallopian tube, attempt should be made to conserve the ovary and fallopian tube by considering ovariopexy. We report a case of parovarian cyst in a 37 year female presenting with an abdominal swelling gradually increasing in size with a provisional diagnosis of a benign unilocular right ovarian cyst made accordingly and was removed surgically and the histopathology revealed its identity.
