Coronary artery aneurysms (CAAs) or ectasias are dilatations of arterial segments, commonly detected as an incidental finding during angiography. The incidence of CAAs varies from 0.3% to 5.3%, mainly caused by atherosclerosis, though infections, inflammatory conditions, and connective tissue disorders can also contribute. Giant CAAs are rare with a reported prevalence of 0.02–0.2%. In our case, a 45-year-old female has been diagnosed with a giant aneurysm in the right coronary artery, which was initially misinterpreted as a pericardial cyst. In addition, she has a bicuspid aortic valve and severe aortic stenosis, hence advised for surgical management.
