Coronary Artery Aneurysm with Associated Fistula: a Rare Condition Detected by Computed Tomography Coronary Angiography

Coronary artery aneurysm with associated fistula is a rare condition. The complete anatomical delineation of this condition can be achieved with multi-detector computed tomography, which has advantages over echocardiogram and catheter angiography because of its ability to show the fistula separate from the surrounding cardiovascular structures, along with any aneurysm or obstruction along its course. Thus, multi-detector computed tomography may be preferred as the initial non-invasive imaging technique for characterisation of these rare congenital anomalies, and may be considered an alternative to conventional coronary angiography for follow-up studies because of its relative non-invasive nature.
