中文摘要 | 海綿狀血管瘤可能發生於中樞神經系統,臨床上通常沒有任何症狀。除非發生出血現象或侵犯到腦幹部位較易產生神經學症狀。而發生於脊椎硬腦膜上之海綿狀血管瘤是相當少見的血管性腫瘤,其磁振造影影像之鑑別診斷有神經瘤、腦膜瘤、淋巴瘤、脊椎血管脂肪瘤、和轉移性腫瘤等。我們報告一81歲男性病例,臨床上表現為漸進性的兩腳麻木及無力約一年之久。磁振造影影像發現一硬腦膜上的腫瘤位於胸椎第二到第五節部位並有向神經孔蔓延現象。討論其磁振造影影像之鑑別診斷及文獻回顧。 |
英文摘要 | Cavernous hemangiomas may affect the cen-tral nervous system, usually asymptomatic and involving the cerebral hemispheres but it may become symptomatic when bleeds or occurs in the brain stem. Purely spinal epidural cavernous hemangioma is a rare benign tumor composed of sinusoid vascular channels. The differential diag-nosis of epidural cavernous hemangioma on MR image includes neurogenic tumors, meningiomas, lymphomas, spinal angiolipoma, and metastasis. We report a case of 81-year-old man presented with progressive numbness and weakness of both lower limbs for one year. MR imaging revealed an infil-trative enhancing epidural tumor at the dorsum of T2 to T5 levels with foraminal extension. The MR image features along with their differential diagnoses are discussed and literature would be reviewed. |
