Cerebral Infarction Caused by Direct Cardiac Tumor Emboli Mixed with Thrombus

Cerebral infarction in cancer patients is often caused by thrombosis due to hypercoagulability, and in some cases, caused by direct tumor embolism. We report the case of cerebral infarction due to direct tumor embolism mixed with thrombus. Biopsy of blood clots obtained during thrombectomy is important for diagnosis. If there is a high risk of thrombosis among cancer patients with cerebral infarction, the use of appropriate antithrombotic agents along with maintaining a certain level of platelets should be considered.
