Pulmonary arteriovenous malformations are abnormal vascular communications between the pulmonary arteries and veins, resulting in an extracardiac right-to-left shunt. Pulmonary arteriovenous malformations are most commonly hereditary and associated with hereditary hemorrhagic telangiectasia. In the current literature, pulmonary arteriovenous malformations have been found to cause hypoxia, ischemic stroke, brain abscess, and hemothorax. Due to these potential complications, transcathether embolization is recommended as a treatment of pulmonary arteriovenous malformations. Here we describe a case of a 25-year-old male with multiple bilateral pulmonary arteriovenous malformations presenting with stroke due to right-to-left shunting.
