Radiologic findings of gastrointestinal complications in an adult patient with Henoch-Schönlein purpura.

Henoch-Schonlein purpura (HSP) is a systemic, generalized vasculitis of small vessels of the skin, joint, gastrointestinal tract, and kidney. Its cause is thought to be an IgA-containing immune complex-mediated autoimmune disease. HSP was originally described in children, but it can also affect adults [1]. It is frequently associated with gastrointestinal involvement, but perforation and stricture are rare because large vessels are unaffected and tend to recover spontaneously and heal without sequelae. To our knowledge, the radiologic findings of gastrointestinal complications in adult HSP have not been reported previously. Herein, we present the radiologic findings of a 54-year-old man who had HSP with small-bowel perforation and stricture. Histopathologic and endoscopic findings were reviewed to diagnose HSP.
