Spinal cord schwannomas are intradural nerve sheath tumors that almost universally occupy a dorsolateral, lateral, or ventrolateral position. Therefore, resection of these lesions typically proceeds via a posterior or posterolateral approach.
We present a case of a midline ventral intradural schwannoma of the cervical spinal cord causing myelopathy. To the best of our knowledge, no previous reports specifically discuss purely midline ventral intradural schwannomas.
Resection of the tumor was performed via an anterior cervical corpectomy with spinal arthrodesis and fixation. We review possible causes for such an anomalous location for schwannoma as well as the advantages and disadvantages of various surgical strategies for removing the tumor.
This case exemplifies the usefulness of anterior approaches to the cervical spine in treating unusual intradural spinal cord tumors.
脊髓神经鞘瘤是硬膜内神经鞘肿瘤，几乎都占据背外侧、外侧或腹外侧位置。因此，这些病变的切除通常通过后路或后外侧入路进行。
我们报告一例颈段脊髓中线腹侧硬膜内神经鞘瘤导致脊髓病的病例。据我们所知，此前尚无专门讨论单纯中线腹侧硬膜内神经鞘瘤的报道。
通过前路颈椎椎体次全切除并进行脊柱融合及固定来切除肿瘤。我们回顾了神经鞘瘤出现这种异常位置的可能原因以及各种切除肿瘤手术策略的优缺点。
该病例例证了颈椎前路入路在治疗不寻常的硬膜内脊髓肿瘤中的实用性。
