a A 52 y/o male with atrial fibrillation presenting with diffuse abdominal pain and guarding. There is a central filling defect (arrowhead) within the SMA approximately 5 cm from the SMA ostium, compatible with acute embolus associated with multifocal pneumatosis (thick arrow) and mesenteric venous gas (thin arrows) consistent with late-stage ischemia. bd A 55 y/o male presented with shock and abdominal pain. Incidental transmural left ventricular hypodensity (asterisk) is seen in RCA distribution, compatible with myocardial infarction. Small filling defect is also noted at LV apex, confirmed to represent a thrombus (curved arrow). Bowel wall thickening (dotted arrow) involves watershed region of sigmoid colon, with predominant mural hypoenhancement suggestive of intermediate stage ischemia
