Scrotal trauma. a Testicular rupture. Longitudinal US of the right testis in a 19-year-old male following jet ski accident. There is disruption of the tunica albuginea (arrowheads) and extrusion of a large amount of the inferior pole of the testis (annotated by letter E); the normal tunica albuginea is noted more superiorly (arrow). Also note surrounding hematocele (asterisk). The patient underwent debridement and repair with preservation of the superior aspect of the right testis. b Testicular fracture. Longitudinal US of the left testis in a 47-year-old who sustained a traumatic scrotal injury after being struck by a baseball traveling at high velocity. The thin hypoechoic band (arrows) corresponds to the testicular fracture line. Orchiectomy was performed due to extent of injury. c Penetrating testicular trauma with intrascrotal gas. Transverse US of the left testis in a 25-year-old who sustained a traumatic scrotal injury after a hand gun discharged while in the patient’s pants pocket. A focal defect (arrow) along the lateral aspect of the left testis corresponds to a site of tunica albuginea rupture and tubule extrusion. A cluster of amorphous echogenic foci with mild posterior shadowing in the testicular parenchyma are due to intratesticular gas. The patient was treated with orchiectomy
