Giant coronary artery aneurysms are rare and have variable presentations, which range from an incidental finding to sudden death. We report a case of a female presenting with chest pain and signs of cardiac tamponade who underwent a computed tomography (CT) pulmonary embolus protocol and was found to have haemopericardium with accumulation of contrast adjacent to the aorta. She underwent emergent sternotomy and was found to have a ruptured giant right coronary artery aneurysm, which was ligated and bypassed. This report highlights the difficulty of diagnosing a ruptured giant coronary artery aneurysm via CT and provides valuable information on an atypical presentation.
