Abstract
Ultrasound was evaluated in 69 patients for its usefulness in distinguishing scrotal abnormalities requiring surgery from those that may have clinical follow-up only. Distinction was possible in the majority of cases. On imaging, tumor showed decreased echogenicity within the testicle, which was usually enlarged. Epididymal enlargement, marked increase in peritesticular fluid, and skin thickening suggest a non tumorous condition. The ultrasound characteristics of various scrotal abnormalities are described.
