A Rare Case of Adult Acute Ileocecal Ischemia Related to Henoch-Schönlein Purpura: MDCT Findings.

Henoch-Schönlein purpura (HSP) is a form of immune complex-mediated leukocytoclastic vasculitis involving the skin and other organs. It primarily affects children. The occurrence of HSP in adults is rare, and gastrointestinal (GI) involvement is one of its most common clinical manifestations. The GI symptoms are caused by hemorrhage and edema within the bowel and wall mesentery. Complete recovery usually occurs, and life-threatening complications are rare. We report a typical case of GI involvement of the ileocecal area diagnosed with multidetector computed tomography (MDCT) and confirmed by skin biopsy.
