Hereditary Angioedema : A Case with Ascites Yet No Symptoms in the Family

An interesting case of hereditary angioedema in a 26-year-old female is reported, with a finding of transient effusion of fluid into the peritoneal cavity during the attacks. The patient suffered from recurrent abdominal pain for several years, but no family members had any similar symptoms. In spite of repeated hospital admissions and manyexaminations, accurate diagnosis was not made until the most recent admission. The recognition of hereditary angioedema as a cause of acute and/or recurrent abdominal pain may avoid useless invasive procedures and lead to adequate treatment in other similar cases.(Internal Medicine 31 : 633-635, 1992)
