Figure 1.   Bowel infarct due to mesenteric arterial occlusion of the ileocolic branch with iodized oil (Lipiodol; Guerbet, Roissy, France) in a 57-year-old man. The iodized oil was infused during hepatic arterial embolization for hepatocellular carcinoma. Contrast material-enhanced CT scan shows bowel wall thickening in the ileum with intestinal pneumatosis (arrowheads), as well as thickening of the ascending colon with the target sign (small arrows). Large arrow = iodized oil.
