[Penetrating atherosclerotic ulcer of the thoracic aorta descendens].

Penetrating atherosclerotic ulcer of the thoracic aorta descendens. HISTORY AND CLINICAL FINDINGS: A 75-year-old man with a history of generalised atherosclerosis was admitted to hospital for invasive assessment of progredient typical angina pectoris. Apart from diminished peripheral pulses, physical examination was normal. INVESTIGATIONS: Coronary angiography revealed a three vessel coronary artery disease. The chest X-ray showed elongation and dilatation of the distal aortic arch and the proximal descending aorta thoracalis. Computed tomography and magnetic resonance imaging of the thorax as well as magnetic resonance angiography of the thoracic aorta, demonstrated a penetrating atherosclerotic ulcer of the descending aorta thoracalis, with extensive intramural hematoma. TREATMENT AND COURSE: After percutaneous ballon-dilatation of the right coronary artery and the circumflex artery, the patient was asymptomatic. Considering all aspects of the patients condition, medical treatment of the penetrating atherosclerotic ulcer was decided for the patient. The findings of the thoracic computed tomography after 6 months were unchanged. CONCLUSION: The penetrating atherosclerotic ulcer of the thoracic aorta is a less known clinical entity. Our case report demonstrates that even extensive forms can be clinical asymptomatic and discovered by routine radiologic examinations.
