Introduction The prevalence and mortality rate of stroke still remains high and of all strokes, 87% are ischemic.1) Cardiogenic embolism explains about 15-30% of ischemic strokes.2)Neoplastic nature of an embolus is unusual and becomes even rarer except for systemic tumor emboli driven by left atrial myxomas. Primary or metastatic neoplasms of the lung are reported to be the more common source of cardiogenic embolus of the neoplastic origin.3) We report a rare case of ischemic stroke in a patient with advanced lung cancer that invaded directly into the left atrium (LA) by way of pulmonary veins.
