AbstractWe describe a case of a 72-year-old woman who presented with two episodes of abdominal pain, vomiting, and diarrhea. Abdominal computed tomographic scans done during each episode demonstrated edema of the small bowel. Review of the patient's history revealed that she had been started on a treatment of lisinopril for hypertension 1 month before the first episode and had her prescribed dose increased 24 hours before each presentation. Angiotensin-converting enzyme (ACE) inhibitor-associated angioedema was suspected and the medication was discontinued. The patient has remained symptom-free while not taking the ACE inhibitor for 1 year. Review of the literature reveals only nine similar cases. All cases, including ours, occurred in women. Angioedema of the small bowel associated with ACE inhibitors is rare and often is not recognized before surgical exploration. Angioedema of the gastrointestinal tract should be considered in symptomatic patients taking ACE inhibitors.
