A right pulmonary angiogram (A) shows a cluster of abnormal vessels in the right mid lung field (arrow) supplied by an artery (arrowhead) and an early draining vein (dashed arrow). Selective angiography of the artery (arrowhead in panel B) confirms the presence of an AVM (arrow) and an early draining vein (dashed arrow).
