Giant right coronary artery aneurysm

Case contributed by Maxime St-Amant
Diagnosis certain


Acute chest pain. Past history of AVR.

Patient Data

Age: 65 years
Gender: Male

Chest x-ray


Ovalar linear calcifications are seen on the lateral chest x-ray, a lot harder to see on the PA. Those look like parietal calcifications; CT-scan is recommended to evaluate the calcifications further.

CT chest


CT-scan shows an aneurysm which seem to originate from the proximal right coronary artery. The aneurysm collar is larger than it would be expected in a pseudoaneurysm. Coronary angiography could be done to further confirm the diagnosis.

Coronary angiogram


Coronary angiography was performed to confirm the diagnosis. Canulation of the right coronary artery's ostium confirms opacification of a giant coronary artery aneurysm.

Case Discussion

Coronary artery aneurysms are rare in adults. Smaller aneurysms can be encountered with Kawasaki disease. The aneurysm was resected.
