title: Hemolytic-uremic syndrome confused with acute appendicitis.
abstract: Hemolytic-uremic syndrome (HUS) may have signs that are clinically indistinguishable from acute surgical diseases of the abdomen. A 2-year-old girl had HUS and physical findings leading to appendectomy. Various pediatric surgical and medical conditions are mimicked by HUS. Attention to specific diagnostic clues (anemia, evidence of hemolysis, thrombocytopenia, azotemia) may lead to the correct diagnosis of HUS and avoidance of an unnecessary operation.
