Abstract We report a patient with hereditary angioedema (HAE) presenting with skin edema and abdominal pain. Laboratory examination showed reduced levels of CH50, C2, C4, and C1 inhibitor (C1-INH). Abdominal computed tomography (CT) showed marked mesenteric edema and wall thickening of the duodenum and transverse colon. Acute abdominal pain is common in HAE and is difficult to distinguish from surgical emergency. Massive mesenteric edema on CT is a rare, but specific, sign suggesting HAE.
Key words Abdominal pain - C1 inhibitor (C1-INH) - Computed tomography (CT) - Hereditary angioedema (HAE) - Mesenteric edema
