title: Case report: ultrasound and MRI findings in a scrotal epidermoid cyst.
abstract: Intrascrotal masses in the adult are worrisome due to their possible malignancy. Most intratesticular masses are malignant whereas most extratesticular masses are benign. The differential diagnosis of intrascrotal cysts usually includes simple testicular cysts, intratesticular epidermoid and dermoid cysts, tunica albuginea cysts, epididymal cysts and spermatoceles [1-7]. This case report describes a large epidermoid cyst of the scrotum presenting as an enlarging scrotal tumour.
