Coronary circulation anomalies are the uncommon cause of chest pain when hemodynamically significant. Multidetector computed tomography (CT) of coronary arteries is rapidly replacing conventional angiography, nowadays, as the first line of investigation for the imaging of coronary artery disease due to its noninvasive nature. CT coronary angiography in addition to diagnosing anomalies of coronary arteries is especially good in the delineation of ostial origin and proximal course. Superdominant right coronary artery (RCA) with absent left circumflex artery (LCx) is such a rare congenital coronary artery anomaly which can mimic atherosclerotic disease clinically with very few case reports in the literature which can be diagnosed and evaluated with accuracy by CT angiography.
