Giant paraovarian cyst in an adolescent: a challenge of accurate diagnostic

Abstract BackgroundParaovarian cysts (POCs) are rarely seen among pediatric female patients. The diagnosis still represents a challenge. Giant POCs are exceedingly rare and only few cases have been reported in the literature.Case presentationA 17-year-old girl from the rural area presented with abdominal pain, pollakiuria and a giant abdomino-pelvic mass. Ultrasound and computed tomography revealed a 14cm x 24cm x 30cm anechoic unilocular cyst which raised the suspicion of a mesenteric or ovarian cyst. The correct diagnosis of left POC was established intraoperatory. Cystectomy was performed. Histopathological diagnosis was serous cystadenoma.DiscussionsPOCs become symptomatic when reach large sizes or complicate, the most feared complication being ovary torsion. Imagistic investigations can establish the diagnosis of cyst, but the cyst’s origin often remains an intraoperatory discovery. Surgical excision is necessary to decrease the risk of complications, and adnexal preservation is essential in pediatric patients. Even for pediatric female patients POC should be considered in the differential diagnosis of cystic abdominal masses.
