A rare cause of acute scrotum in a child: torsion of an epididymal cyst. Case report and review of the literature.

Torsion of an epididymal cyst is an extremely rare cause of acute scrotum in children and in young boys. Its reported incidence is 5-20%. The treatment is usually conservative. Many cases (up to 60%) regress spontaneously, especially if below 3 cm. Few cases have been reported in Literature (7 cases/2018). We add our patient as eighth case. He was a 13-year-old boy who was admitted for acute scrotum. Ultrasound excluded torsion of the testis and he was managed for 5 day conservatively. Based on clinical history and physical exam, we decided to perform a prompt surgery that revealed a torsion of epididymal cyst that was confirmed by histological exam.
