Toddler with right scrotal pain who had suffered non-accidental trauma

CT of testicular hematoma
Axial CT with contrast of the abdomen (above) shows a heterogenous appearance to the enlarged right testicle which is surrounded by an edematous scrotal sac. Sagittal US of the right scrotum (below) again shows the thickened edematous scrotal sac, the heterogenous testicle, and an anechoic fluid collection surrounding the testicle.

The diagnosis was testicular hematoma surrounded by a reactive hydrocele and a scrotal hematoma secondary to trauma.
