Diagnosis of anomalous origin of left coronary artery from pulmonary artery in an adult by 64-slice CT angiography.

Anomalous origin of Left Coronary Artery from Pulmonary Artery (ALCAPA) presenting in adult age is a rare entity. We report an adult patient with exertional angina, who was diagnosed to have ALCAPA conclusively and non-invasively by 64-slice CT angiography.
