Pulmonary arteriovenous malformation
Coronal maximum intensity projection from a chest CT (image 1) demonstrates a pulmonary arteriovenous malformation (arrow), confirmed with pulmonary angiography (images 2 and 3). Pulmonary arteriovenous malformations, which are abnormal connections between the pulmonary artery and vein, create an intrapulmonary right-to-left shunt. They are more common in patients with hereditary hemorrhagic telangiectasia.
