Angiotensin Converting Enzyme (ACE) Inhibitor Associated Small Bowel Angioedema and Ascites Presenting as Recurrent Acute Abdomen: A Case Report

Abstract

We describe a case of a patient who presented with recurrent abdominal pain due to small bowel angioedema believed to be caused by a recently started ACE inhibitor with classic imaging features. Very few cases of visceral angioedema due to ACE inhibitor use are described in the literature. This case demonstrates a unique direct causal association between the onset of drug administration and symptomatic bowel angioedema as well as ascites, spontaneous resolution on stopping ACE inhibitor, and recurrence of acute clinical symptoms and imaging features on resumption of the drug.
