The utility of scrotal ultrasonography in the emergent setting: beyond epididymitis versus torsion.

Scrotal pain is a common acute presentation for medical care. Testicular torsion and epididymo-orchitis are two diagnoses for which early detection is critical and their sonographic imaging features have been thoroughly described in the radiologic literature. Other important conditions for which radiologists must be aware have received less attention. This article will highlight key traumatic and non-traumatic causes of acute scrotal pain other than testicular torsion and epididymo-orchitis that may present in the emergency department setting.
