Simple testicular cyst in infants: a case report and review of the literature

We report a 5-month-old boy with testicular cyst. He presented with a right inguinal hernia and a scrotal mass. Ultrasonography showed a cystic mass in the right testicular parenchyma, suggesting a testicular cyst. He underwent right herniotomy and unroofing of the cyst. Simple testicular cyst is extremely rare with only 48 cases reported in the literature. Of these cases, 8 patients were less than two years old. The diagnosis of simple testicular cyst can be made preoperatively with ultrasonography. Testis-preserving excision or unroofing the cyst is the treatment of choice.
