From: Chest CT examinations in patients presenting with acute chest pain: a pictorial review
A 53-year male patient with history of pulmonary artery stenosis, presented with exertional chest pain. ECG showed ST segment depressions and left ventricular hypertrophy. At invasive coronary angiography, it was not possible to selectively catheterize the right coronary artery. An aneurysm was observed but the exact location remained unclear. Patient underwent coronary CTA for locating the aneurysm and imaging the right coronary artery. (a-c) CTA with maximum intensity and volume rendering reconstructions shows 5.9 × 5.2 × 5.2 cm diameter aneurysm of the right sinus of Valsalva (RSV). (a) axial image showing relation with the normal aortic root. (a-c) The RCA was stretched out over the RSV aneurysm that caused some narrowing of the RCA lumen. No atherosclerotic coronary artery stenoses were found
