Striated Appearance of the Testes

Striated testis is an occasional ultrasound finding in symptomatic and asymptomatic individuals. In older men, the finding of striated testis usually corresponds to a diagnosis of interstitial fibrosis and requires no further action. However, in the appropriate clinical setting, the differential diagnosis of striated testis also includes infection, infarction, trauma, and neoplasm. In this pictorial review, we present the varied sonographic appearances of striated testis within these clinical contexts.
