AbstractThis is a case report on a 45-year old African-American female with newly diagnosed hypertension, who was started on a combination pill of amlodipine/benazapril 10/5 mg. The very next day, she presented at the emergency room (ER) with abdominal pain, nausea and vomiting. Physical exam, complete metabolic panel, and hemogram were in the normal range. She was discharged from the ER after a few hours of treatment with fluid and analgesics. However, she returned to the ER the next day with the same complaints. This time the physical exam was significant for a distended abdomen with dullness to percussion. CT scan of the abdomen revealed markedly thickened antrum of the stomach, duodenum and jejunum, along with fluid in the abdominal and pelvic cavity. Angiotensin-converting enzyme inhibitor (ACEI)-induced angioedema was suspected, and anti-hypertensive medications were discontinued. Her symptoms improved within the next 24 hours, and repeat CT after 72 hours revealed marked improvement in stomach and small bowel thickening and resolution of ascites. The recognition of angiotensin-converting enzyme (ACE) and angiotensin receptor blocker (ARB) intestinal angioedema constitutes a challenge to primary care physicians, internists, emergency room personal and surgeons.
