Case 4. Contrast-enhanced computed tomography of the abdomen (a) showed circumferential wall thickening and heterogeneous enhancement with layers of low attenuation consistent with colonic edema. Pathological analysis of colectomy specimen revealed severe necrosis with complete loss of crypts, hemorrhage and infiltration of the colon by inflammatory cells (b, hematoxylin-eosin-saffron stain, x200). Small-vessel vasculitis was observed with fibrinoid necrosis and vessel wall infiltration by neutrophils (c, hematoxylin and eosin stain, x400).
