[Cervical myelopathy from an aspect of a neurological surgeon].
More than 65 per cent of intramedurally tumors and intradural extramedurally tumors were located in cervical region. They enact a cause of cervical myelopathy. A special attention should be paid to solitaly intramedurally vascular malformations, when the patients show an acute progressive myelopathy. In very rare cases of syringomyelia, intramedurally tumors such as hemangioblastoma or ependymoma could be found, so that enhanced MRI or angiography should be done if necessary. In cases of a herniated disc, cervical spondylosis and OPLL, the distance between articulo-pillar line and spinolaminal line must be measured. If the distance of both lines is near or the same, that means narrow cervical canal. In rare cases the form of the vertebral body is round. This is a rare cause of a type of narrow canal.
