Three cases of cystic testicular disease: simple cyst of the testis, cyst of the tunica alubuginea and mature cystic teratoma

摘要

We experienced three cases of cystic testicular disease including simple cyst of the testis, cyst of the tunica alubuginea and mature cystic teratoma. Cystic testicular diseases have been considered rare, but increasing usage of ultrasound in the diagnosis of scrotal diseases has made them more common. Ultrasonography seemed to be useful to distinguish nonneoplastic testicular cysts (simple cyst of the testis, cyst of the tunica alubuginea) from cystic lesions of solid testicular tumors.
