Melanocytic lesions of the nervous system are thought to arise from leptomeningeal melanocytes, which are derived from neural crest and include diffuse melanocytosis, melanocytomas, and malignant melanomas. Meningeal melanocytomas are extremely rare benign lesions. The usual treatment of intradural extramedullary melanocytomas involves surgical removal through a posterior approach using a laminectomy or laminotomy.
We present a 30-year-old female harboring a C6-T1 ventrally located intradural extramedullary lesion compressing the cord anteriorly. The lesion was totally resected via an anterior approach with oblique corpectomy even if the usual treatment involves surgical removal through a posterior approach using a laminectomy or laminotomy.
There is no evidence of recurrence at 4-year follow-up records of the patient. We discuss the surgical approach of these rare lesions.
神经系统的黑素细胞性病变被认为起源于软脑膜黑素细胞，其源自神经嵴，包括弥漫性黑素沉着症、黑素细胞瘤和恶性黑色素瘤。脑膜黑素细胞瘤是极其罕见的良性病变。硬膜内髓外黑素细胞瘤的常规治疗包括通过椎板切除术或椎板切开术经后路进行手术切除。
我们报告一名30岁女性，其C6-T1水平存在一个位于硬膜内髓外且向前压迫脊髓的病变。即使常规治疗是通过椎板切除术或椎板切开术经后路进行手术切除，但该病变还是通过前路斜行椎体切除术被完全切除。
在患者4年的随访记录中没有复发迹象。我们讨论了这些罕见病变的手术入路。
