The radiology of enteritis due to hemolytic-uremic syndrome.

The hemolytic-uremic syndrome is a distinct entity of variable severity and unknown etiology characterized by hemolytic anemia, renal failure, and thrombocytopenia. Some patients present with a gastrointestinal prodrome prior to the development of renal failure. Radiologic features include submucosal edema, spasm, and superficial ulcerations. There may be subsequent post-ischemic stricture formation. When these non-specific radiologic features are correlated with patient age, clinical history, and peripheral blood smear, the radiologist may be the first to suggest the diagnosis of hemolytic-uremic syndrome.
