Diagnosis of Henoch-Schönlein purpura by sonography and radionuclear scanning in a child presenting with bilateral acute scrotum.
Acute scrotum presenting as the only initial manifestation of Henoch-Schönlein purpura (HSP) is so unusual that the diagnosis can easily be missed. We report this condition in a 4-year-old boy admitted with bronchopneumonia. Bilateral painful scrotal swelling with ecchymosis occurred on the second day of hospitalization. Scrotal sonography was performed and a good blood supply was documented. Scrotal nuclear scanning was performed and was consistent with bilateral epididymoorchitis. Multiple purpuric lesions over the lower extremities and perineal region developed on the third day of hospitalization. Intermittent abdominal pain and knee pain developed thereafter. HSP was diagnosed and steroids were prescribed. The symptoms subsided gradually and no complication was noted. This case reminds us that an acute scrotum may be the only initial manifestation of HSP. Sonography and nuclear scanning can help rule out other diseases.
