Testicular involvement in patients with Henoch-Schönlein syndrome may occur in as high as 15 per cent of the cases. Scrotal imaging is extremely accurate in differentiating hyperemia (vasculitis) from impairment of blood flow encountered in torsion of the spermatic cord, the most common cause of acute scrotal swelling in children.
