Unresolved chronic diarrhea: A case of ACEI-induced mesenteric angioedema

Angiotensin-converting enzyme inhibitors (ACEI) are frequently prescribed for cardiovascular and renal diseases. However, ACEI-induced visceral angioedema is a rare occurrence that often goes unnoticed and poses a diagnostic challenge due to its non-specific and diverse symptoms. Key diagnostic indi...

Description
Summary:Angiotensin-converting enzyme inhibitors (ACEI) are frequently prescribed for cardiovascular and renal diseases. However, ACEI-induced visceral angioedema is a rare occurrence that often goes unnoticed and poses a diagnostic challenge due to its non-specific and diverse symptoms. Key diagnostic indicators on a CT scan include the ‘target’ sign, elongation of bowel loops, enlarged mesenteric vessels, mesenteric edema with or without ascites, thickened omentum, and the absence of vascular compromise or adenopathy. Discontinuation of ACEI usually results in symptom resolution within 48 hours. While this phenomenon is more commonly observed in females and African Americans, we present a case of a Caucasian male who underwent an extensive diagnostic evaluation, including exploratory surgery, before ACEI-induced angioedema was considered.
