The role of ultrasound in scrotal trauma.

We reviewed the sonograms of 16 cases with scrotal trauma and documented the spectrum of abnormalities that may be present in sonography after a scrotal injury. The sonographic findings included scrotal hematoceles, post-traumatic epididymitis, epididymal hematoma, testicular hematoma and/or infarction, testicular rupture, testicular swelling and hyperemia. Ultrasound is able to distinguish intratesticular and extratesticular lesions. The integrity of the testis could be evaluated as well. It should be the imaging modality of choice for the evaluation of scrotal trauma.
