title: The use of ultrasound for evaluating subacute unilateral scrotal swelling.
abstract: In 15 patients with subacute (longer than 8 hours) unilateral scrotal swelling in whom the etiology was in doubt scrotal ultrasound was used to determine whether the pathological condition was intratesticular and/or extratesticular. Surgical exploration confirmed intratesticular or intratesticular and extratesticular findings in 9 patients: 8 had torsion of the spermatic cord (including a testis rupture in 1 and epididymal ruptures in 2) and 1 had a mixed germ cell carcinoma. Of the 6 patients with extratesticular findings 3 had clinical epididymitis that resolved on antibiotic therapy and 2 had what appeared to be paratesticular hematomas with normal testes presumed to be secondary to minor trauma. The condition resolved with conservative therapy in the latter 2 patients. The remaining patient required surgical drainage because of the size and an epididymal rupture suspected by the ultrasound examination. Scrotal ultrasound is a quick, noninvasive, easily applied, accurate method to diagnose scrotal pathological conditions and should be used whenever the etiology of scrotal swelling is in doubt.
