Acute Ischemic Stroke Caused by Primary Pulmonary Adenocarcinoma with Extension to the Left Atrium

ABSTRACT

Malignancy-related cerebral embolism, which is generally attributed to hypercoagulability, is an uncommon cause of ischemic stroke. However, ischemic stroke developed with intracardiac extension of lung cancer has rarely been reported. We report a case of acute embolic stroke caused by pulmonary adenocarcinoma that invaded the right inferior pulmonary vein and extended into the left atrium. Microembolism developing as a result of lung cancer may have been the cause of stroke in this case.
