The sonographic diagnosis of focal and diffuse infiltrating intrascrotal lesions.

Thirty-six examples of inflammatory and neoplastic disease of the scrotum were evaluated with ultrasound. Analysis of the images suggests that sonographic differentiation of these conditions is possible in certain instances. The ability to separate testicular from extratesticular pathology is quite accurate. In some cases, neoplastic disease of the testis can be differentiated from malignancy, although surgical intervention is often required for diagnosis.
