摘要
神经鞘瘤是椎管内最为常见的良性肿瘤之一,好发于髓外硬膜内,临床表现以神经根痛及运动功能障碍为主,肿瘤大小一般不超过2个椎体,但部分椎管内神经鞘瘤可生长至巨长型,甚至经椎间孔向椎管外生长呈巨大哑铃型。作者报告1例男性37岁,患双下肢麻木、乏力、肌肉萎缩4年余,加重并出现行走困难、大小便费力2年。MRI检查发现为第11腰至第3骶巨长型椎管内肿瘤,经显微神经外科手术将肿瘤整块完全切除并行脊柱内固定术,肿瘤纵轴长度达33cm,病理证实为神经鞘瘤。术后患者恢复良好,大小便功能和双下肢肌力恢复正常。经文献检索,未见有如此长的椎管内神经鞘瘤的报道。
Neurilemmoma is a common and benign intraspinal tumor. Neuralgia of spinal nerve roots and motor dysfunction are the common clinical manifestations of intraspinal neurilemmoma. The length of the tumor usually does not exceed two vertebral bodies. But in some cases, the tumors may grow into a giant dumbbell-shape mass extending from intraspinal canal through intervertebral foramen into extra-spinal spaces. We reported a rare case of such. He was a 37-year-old man with 4 years history of numbness, weakness an...
