Primary Intraspinal Mesenchymal Chondrosarcoma: Report of One Case

我們報告一個11歲男童被診斷為原發性脊髓內間葉軟骨肉瘤之病例。磁振造影呈現在左側第七頸椎至第二胸椎處有一個高訊號臘腸狀之腫塊，位於脊髓之前外側並將脊髓推至右後方。顯微鏡及免疫組織化學染色法檢查確定診斷為間葉軟骨肉瘤。追蹤2年後並無腫瘤復發之現象。此腫瘤雖然罕見， 但仍應列入脊髓腫瘤之鑑別診斷。
We report a case of primary intraspinal mesenchymal chondrosarcoma in an 11-year-old boy. Contrast-enhanced MRI revealed a hyperintense, sausage-shaped mass extending from C7 to T2. The lesion located anterolaterally on the left side, pushing the spinal cord to the right and posterior. Microscopic examination and immunohistochemical studies confirmed the diagnosis of mesenchymal chondrosarcoma. Follow-up studies have shown no tumor recurrence for 2 years. This tumor is rare but should be considered for differential diagnosis in spinal tumors.
