Penetrating aortic ulcer [PAU] is an uncommon but potentially life-threatening entity within the spectrum of acute aortic syndromes [AAS]. Early diagnosis is essential to prevent complications such as intramural hematoma, pseudoaneurysm formation, dissection, or rupture. We report the case of a patient presenting with acute chest pain in whom computed tomography angiography [CTA] revealed a penetrating ulcer of the descending thoracic aorta. The imaging findings, differential diagnoses, management considerations, and literature review are discussed with emphasis on the radiologist’s role in early recognition and follow-up.
