Histopathologic evaluation of emboli retrieved via mechanical embolectomy in acute ischemic stroke can rarely identify tumor emboli such as undifferentiated sarcoma.
Embolus histopathology during thrombectomy may reveal occult sarcomas; leaves open targeted screening utility in cryptogenic stroke.
Tumor emboli due to a sarcoma are usually confirmed by an autopsy or operative findings. A sarcoma embolus in an acute stroke patient is rare. We herein report a 37-year-old man with acute stroke caused by internal carotid artery occlusion who underwent embolectomy. A histopathological analysis of an embolus obtained with a mechanical retriever device was diagnosed as undifferentiated sarcoma. This is the first case of extracardiac sarcoma extraction via mechanical retrieval performed during intervention for acute ischemic stroke. A histopathologic evaluation with embolectomy is important for diagnosing tumor emboli.
