Scrotal masses with a uniformly hyperechoic pattern.

Eight scrotal masses which appeared homogeneously hyperechoic on ultrasound were studied; 5 were testicular and 3 were extratesticular. Pathologically, there was no evidence of malignancy, and most lesions consisted of scar tissue or fibrosis. Two benign adenomatoid tumors were encountered. In this series, a homogeneously hyperechoic scrotal lesion was benign regardless of its location.
