We report a case of variant origin of the right coronary artery from the left posterior aortic sinus. This was observed routinely during a medico legal autopsy of a 58 year old male who died in a road traffic accident. Initially it was believed that the right coronary artery was absent since there was no obvious right coronary artery ostium from the anterior aortic sinus. However it was found later that the right coronary ostium was present just beside the left coronary ostium in the left posterior aortic sinus and the right coronary artery was arising from the left posterior aortic sinus. The right coronary artery had an intramural course between the aorta and pulmonary trunk, which is considered as very dangerous and life threatening. We believe that the present case report will be enlightening to the cardiologist and cardiothoracic surgeon. It is also true that the conduction of medico legal autopsies of coronary arteries is important for the medico legal resolution.

KEY WORDS: Aortic Sinus; Coronary Artery Ostium; Right Coronary Artery; Left Coronary Artery.
