Cystic dysplasia of the testis: sonographic and pathologic findings.

Sonographic and laboratory findings are presented for a case of left-scrotum testicular cysts in a 30-year-old man. Previously reported cases of this rare congenital malformation have occurred in infants and young boys. The patient showed previous evidence of the cyst at age 13. Sonographic images correlated well with previously published gross and microscopic descriptions.
