呈亚铃型生长的椎管内肿瘤并非少见.文献统计约占椎管内肿瘤的5.7～14.2%其中颈段占33～57.5%,胸段占34-42%,腰骶段占8.5～25%.在胸、颈段者多为神经元性肿瘤,其中胸段占92.6%、颈段占85.2%.椎管内—纵隔的亚铃型肿瘤有13.2%为后纵隔神经元性肿瘤.这种肿瘤的病程与一般椎管内神经纤维瘤无特殊差别,椎间孔扩大及脊椎骨质破坏和萎缩较明显.作者提出以下主要诊断根据:1.临床上有神经根刺激症状或脊髓受压表现,脑脊液检查、脑脊液动力学以及脊髓造影等阳性资料.2.X线摄片发现相应椎间孔扩大和破
An intraspinal tumor with sub-bellied growth is not uncommon. The literature statistics account for 5.7-14.2% of the tumors in the spinal canal, of which 33-57.5% are in the cervical segment, 34-42% in the thoracic segment, and 8.5-25 in the lumbosacral segment % .In the thoracic and cervical segments were mostly neuronal tumors, which accounted for 92.6% of the thoracic segment, cervical segment accounted for 85.2% .Intervertebral - mediastinal sub-bellied tumors 13.2% of the posterior mediastinal neuronal tumors. The course of the tumor with the general spinal neurofibroma no special difference, foraminal expansion and vertebral bone destruction and atrophy more obvious.The author proposes the following main diagnostic basis: 1 clinical symptoms of nerve root irritation or spinal cord compression Performance, cerebrospinal fluid examination, cerebrospinal fluid dynamics and myelography and other positive data .2.X ray found the corresponding foraminal expansion and broken
