Transient Ischemic Attack, the Initial Presentation of Azygos to Pulmonary Vein Fistula

Abstract

There are different sources of cerebral emboli, including cardiac embolism, extracranial arterial embolism, paradoxical embolism, trauma, and iatrogenic embolism. In rare cases, atypical sources should be ruled out. We are reporting a lady who presented with transient ischemic attack and had a fistula between the azygos to the pulmonary vein. (Level of Difficulty: Advanced.)
