Why the study?
Cardiac myxomas are typically hypovascular tumors with sparsely distributed vessels, and reports of myxoma with rich blood supply are rare.
Highlights a rare presentation of cardiac myxoma with rich blood supply, which may appear different on contrast echocardiography and CTA compared to typical hypovascular myxomas.

Rare hypervascular left atrial myxoma on CE/CTA expands imaging spectrum; hypothesis-generating and should not yet change practice.
Cardiac myxoma is the most common primary benign cardiac tumors, mostly found in the left atrium. It was previously reported that the main component of myxoma was myxoid stroma riched in acid-mucopolysaccharide, the blood vessels in which were sparsely distributed, being characterized as hypovascular tumor by contrast echocardiography (CE) and computed tomography angiography (CTA). There are few reports of myxoma with rich blood supply and we report one in the left atrium.
