title: Acute abdominal attack of hereditary angioneurotic oedema associated with ultrasound abnormalities suggestive of acute hepatitis.
abstract: Hereditary angioneurotic oedema (HANO) is an autosomal dominant disorder caused by a deficiency of the inhibitor protein Cl-esterase. Recurrent subcutaneous and/or submucosal oedema formation is a hallmark of this disease. HANO is a rare, but potentially life-threatening disorder with a mortality around 20-30%. Acute oedematous abdominal attacks of HANO can mimic a surgical emergency; this is exemplified by the case of a 14-y-old male patient with HANO admitted for such clinical manifestations.
  
  
  CONCLUSIONS
  Diagnostic clues include ascites and abnormalities of hepatic structure visible with ultrasound during the oedematous attack. The importance of appropriate treatment is emphasized.
