[Hereditary angioedema causing colocolic intussusception]

Hereditary angioedema is a rare, autosomal dominant disease inherited. The cause is a quantitative or qualitative congenital deficit in C1 inhibitor. Various clinical symptoms, in particular of sub-cutaneous, upper airways and digestive origin, have been described. Life threatening conditions may be observed. Little information is available on digestive tract localization corresponding to intestinal intussusception associated with hereditary angioedema in children. We report a case of hereditary angioedema observed in a 15-years-old girl who presented such features. We propose a review of the literature and discuss the curative treatment of digestive crisis in children with hereditary angioedema.
