中文摘要 | 神經腸膿腫是造成幼兒及小孩脊髓壓迫罕見的原因。這些先天性的異常是因為再胚胎發育時,內胚層與神經外胚層不正常的分離所造成的。神經腸囊腫的術前診斷並不容易。我們在此報告二例患有神經腸囊腫的病例,並回顧相關文獻。磁振造影對神經腸囊腫的術前診斷及手術計劃,均能提供相當有用之訊息。神經腸囊腫在手術切除之後,神經系統之功能往往能完全恢復,但是其術後復發率仍有待商榷。當脊椎管中出現囊腫狀病灶時,我們必須將神經腸囊腫的可能性列入考慮。 |
英文摘要 | Neurenteric cysts are rare causes of spinal cord compression in infants and children. These congenital lesions arise from abnormal separation of the endoderm and neuroectoderm during embryogenesis. A diagnosis of neurenteric cysts prior to surgery is difficult. Herein, the authors report on 2 cases with neurenteric cysts. The preoperative MR images of both cases showed cystic lesions with low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, just like the intensity pattern of cerebrospinal fluid. One was intradural extramedullary and the other was intramedullary in location. The literature is also reviewed. |
