A 25-year-old man with distal myopathy was admitted to our institution because of sudden abdominal pain. Color Doppler sonography showed a marked decrease in blood flow in the superior mesenteric artery, leading to a diagnosis of intestinal congestion. This finding was confirmed by subsequent angiographic examination. Laboratory tests indicated protein C deficiency (PCD). Intensive medical treatment with warfarin improved the clinical symptoms and color Doppler findings simultaneously. These results suggest that PCD should be considered in all cases of thromboembolic disease of unknown origin, and that color Doppler sonography should be performed first when patients with PCD have abdominal symptoms.
