Chronic Periaortitis of Ascending Aorta With Bilateral Ostial Coronary Stenosis in a Young Female.

An 18-year-old woman without any risk factors for coronary artery disease or systemic vasculitis and infection presented with recurrent angina at rest. Coronary angiography revealed 100% occlusion of the ostial left main coronary artery and severe ostial right coronary artery stenosis. She underwent successful coronary artery bypass graft surgery. At surgery, the external surface of the ascending aorta was covered with a soft-tissue thickened mass; histopathology of the mass revealed chronic nonspecific inflammatory aortitis.
