title: High-resolution ultrasonography of scrotal pathology.
abstract: A prototype high-resolution (10-MHz) real-time ultrasonic system was used to study 22 patients who were ultimately proved to have intra- and extratesticular tumors, scrotal fluid collections, and inflammatory processes. In 5 of 6 patients with primary testicular masses, there were areas of decreased echogenicity within the testis when compared with surrounding normal tissue. In general, the method was highly effective in differentiating and characterizing testicular and extratesticular processes.
