Pulmonary arteriovenous malformation (PAVM) is an abnormal direct capillary free communication between pulmonary arteries and veins which results in a right-to-left intrapulmonary shunt. Depending on the size and number of these vascular malformations and degree of the right-to-left shunt, PAVM can present with dyspnea, cyanosis or paradoxical embolism. Paradoxical embolism from a previously unknown isolated PAVM is a rare cause of ischemic stroke which is usually overlooked in most cases at the initial presentation. Transcatheter embolization (TCE) is the gold standard treatment for these PAVMs which decreases the risk of paradoxical embolism and other associated complications.

Here, we report a case of a young female presenting with acute ischemic stroke secondary to paradoxical embolism from an undiagnosed PAVM. We also review the related literature.
