Nonocclusive mesenteric ischemia, Miliary high echo, Pneumatosis intestinalis, Scattered dendrite-like low density area
We examined three cases of nonocclusive mesenteric ischemia that showed transiently the characteristic ultrasonographic images i. e. "miliary high echo findinds" in the liver and thickening of the intestinal wall. A scattered dendrite-like low density area was also seen in the liver by CT scan in one case. In contrast, no similar findings were recognized in 63 patients who underwent surgery for intestinal obstructions. We believe that the findings in the liver are due to gas in the portal area, not the biliary tract, judging from past history, surgical specimens and microscopical examinations. The miliary higt echo and scattered dendrite-like low density area in the liver suggest the existence of ischemic lesions of the small intestine.
