Abstract

Hereditary angioedema (HAE) is a relatively rare clinical entity that can potentially cause life-threatening airway or intestinal oedema, patients with the latter usually presents with symptoms of gastroenteritis like vomiting, diarrhoea and abdominal pain. Here, we present a unique case of a less recognised type of HAE that is type III in a patient who presented with signs and symptoms consistent with infectious colitis. She previously had similar episodes and was managed multiple times with antibiotics, with no satisfactory response. There, she underwent extensive diagnostic evaluation. On the basis of findings of further investigations on the current visit, she was eventually diagnosed with intestinal angioedema. To the best of our knowledge, the present paper represents the third reported case of type III HAE-induced intestinal angioedema. Additionally, we undertake a literature review of HAE.
