Ischemic stroke involving multiple artery territory with normal vessels gives a clue for an embolic stroke. Paradoxical embolization is a recognized cause of ischemic stroke. We describe a 48-year-old male who presented with acute onset giddiness, mild dysarthria, right hemiparesis, and ataxia. Clinical examinations indicated left cerebellar signs with right hemiparesis. Additionally, the patient had significant clubbing and mild cyanosis. A strong family history of epistaxis and hemoptysis was noted. His Magnetic resonance imaging of the brain showed acute left cerebellar and left frontal cortical infarct with normal vessels. The routine stroke and cardiac workup were normal. Chest X-ray showed bilateral lower zone opacities. Contrast-enhanced computerized tomogram (CT) of the chest showed bilateral pulmonary arteriovenous malformation. Paradoxical embolism due to pulmonary arteriovenous malformation resulted in ischemic stroke in our patient. He fulfilled all of the four criteria for diagnosing definite hereditary hemorrhagic telangiectasia. Our case highlights the importance of a systematic search for paradoxical embolism in a cryptogenic stroke.
