| 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. |
