Endovascular Thrombectomy in a Patient with Acute Ischemic Stroke due to Tumor Emboli Associated with Cardiac Metastasis of Extraskeletal Myxoid Chondrosarcoma: A Case Report

Cardioembolic stroke caused by tumor emboli is a rare form of cancer-associated stroke. We report a case of a patient with cardiac metastasis of extraskeletal chondrosarcoma who developed left internal carotid artery occlusion due to embolic stroke. Extraskeletal chondrosarcoma is an extremely rare subtype of soft tissue sarcoma characterized by a tendency for local recurrence and metastasis. Endovascular thrombectomy was performed using a combined technique, achieving complete revascularization. Histopathological analysis of the retrieved cell mass confirmed that the embolic source was the preexisting extraskeletal chondrosarcoma.
