Non-Tender Huge Abdominal Mass in an Adolescent

Abstract

Paraovarian cysts constitute about 10% of all adnexal masses in females and occur most commonly in the third and fourth decades of life. These cysts are benign and usually uncommon in adolescence. Such cysts pose a diagnostic challenge while distinguishing them from ovarian cysts clinically and during radiological investigations. We report a rare case of a 13-year-old female patient with bilateral paraovarian cysts, including a giant cyst in right mesosalpinx presenting to Sohar hospital, Oman in 2018. The definitive origin of the huge mass on the right side of abdominal cavity could not be established in the current case despite contrast enhanced computerized tomography. It was only on laparoscopic exploration that this mass was identified as a giant paraovarian cyst. Both the giant cyst and a smaller paraovarian cyst on the left side were enucleated with minimally invasive surgery while preserving the fertility of the patient. Only one other similar case of bilateral paraovarian cysts in an adolescent, including a giant cyst managed with laparoscopy, has been documented previously.
