Here, we describe a case of a tumorigenic embolism in a patient with lung cancer whose invasion into the vascular system was not detected on preoperative whole-body imaging. Case Description: A 66-year-old man who was hospitalized to undergo radiotherapy for pulmonary carcinoma suddenly developed left hemiplegia. He exhibited atrial fibrillation, and emergent radiographic examination revealed a right middle cerebral artery occlusion. Urgent mechanical embolectomy was performed, with successful revascularization. The excised embolus had a unique morphology and was pathologically diagnosed as a cerebral embolism caused by pleomorphic pulmonary carcinoma. Conclusion: Tumor-derived cerebral embolism is extremely rare, but it is necessary to consider it as a potential source of embolism during differential diagnosis in patients with malignant tumors.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/c0a7e402-9de7-4c5d-94f9-d6e43ece383b/featured/hero-1781563277256.png","publishDate":"2020-08-01T00:00:00.000Z","doi":"10.25259/SNI_37_2020","categories":["Neurovascular","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2020/08/10171/SNI-11-217.pdf"}
