摘要


脊椎內腸原性囊腫(Intraspinal enterogenous cyst)是一種極爲少見的疾病。自1934年迄今文獻上只有50多個病例報告。 本文報告一名13歲男童,他在3歲和6歲時曾有過暫時性的下肢無力,數個月後自行恢復。這次住院前兩週,他再度感到下肢無力,且逐漸嚴重至無法行走,因此至本院治療。經脊髓攝影及電腦斷層檢查,發現硬膜內脊髓外病變。手術時,在第七至第九胸椎脊髓的右後方發現一囊腫組織,並將脊髓往左前方擠壓,囊腫內含有透明黏液狀液體。病理切片發現富含黏液素(mucin)的單層上皮細胞。該黏液素以PAS及Alcian Blue染色均呈陽性反應。經手術治療後,病人恢復得極爲良好。 脊椎內腸原性囊腫病患,臨床上並無獨特的臨床表現或病史,其初期症狀常以疼痛及四肢無力來表現,逐漸合併一些其它的神經異常症狀,且與囊腫所導致的脊髓壓迫位置與程度有關。唯一的治療方法是手術切除。在早期手術切除後,預後非常良好。在過去的文獻報告中,曾有三例在長期追蹤後(6至14年),發現復發,因此,長期追蹤非常重要。

A 13-year-old boy with an intradural extramedullary enterogenous cyst is presented. He presented with progressive weakness of lower limbs. The myelography and computed tomography scan of spinal cord demonstrated an intradural, extramedullaly lesion at the spinal level of T 7-9. A cystic lesion was discovered during operation. The cyst caused the spinal cord compression and was related to neurological deficit. Histologically, it was confirmed by Periodic Acid-Schiff and Alcian Blue stain to contain mucin. He recovered very well after surgical removal of the cyst.
