Huge Spinal Extradural Meningeal Cyst in the Thoracolumbar Spine: A Case Report of a Rare Cause of Low Back Pain
胸腰脊椎內之巨大硬脊膜外腦脊膜囊腫：罕見的下背痛原因－病例報告
摘要
有症狀之脊椎內硬脊膜外腦脊膜囊腫相當罕見。本文描述一位17歲的女性，主訴持續一年的下背痛，伴隨雙側下肢及右腰漸進性的酸麻。核磁共振影像檢查及電腦斷層脊髓攝影顯現一巨大脊椎內硬脊膜外腦脊膜囊腫，範圍分佈自胸椎第十二節至腰椎第三節，造成前側脊髓及脊膜腔嚴重的壓迫。病患接受胸腰椎手術，發現硬脊膜有一處缺損與囊腫內交通，於是將囊腫後壁切除並修補脊膜腔與囊腫之交通缺損處。組識病理顯示該囊腫壁為無特異性之纖維結締組識，與脊椎內硬脊膜外腦脊膜囊腫之診斷吻合。患者之症狀在手術後完全緩解，於門診持續追蹤兩年後之核磁共振影像檢查亦無發現復發跡象。我們回顧相關文獻並且探討其臨床表徵、可能的致病機轉、影像檢查、鑑別診斷及病理組識之特性與治療方式及預後。

Symptomatic intraspinal extradural meningeal cysts are rare. We present the case of a 17-year-old female with low back pain, progressive numbness, and radiation pain to the flank and lower limbs. Magnetic resonance imaging and computed tomographic myelography revealed a huge intraspinal extradural meningeal cyst extending from T12 to L3 with cord and dural sac compression. The patient underwent surgery to open the cyst and close the connecting dural defect. Pathologic examination of the cyst disclosed non-specific fibrous connective tissue without an inner arachnoid single-cell lining. She achieved complete recovery after the operation. There was no recurrence of the cyst at a 2-year follow-up.
