[Evaluation of expansive myelo-vertebral pathology using different radiologic modalities, magnetic resonance...

The authors review their personal experience in tumors of the spine and the spinal cord, based on 30 cases evaluated with plain x-ray film of the spine, plain Computed Tomography (CT), myelography and myelo-CT. The value of both plain film of the spine and CT in tumoral lesions involving the skeleton is assessed; however, as far as nervous structures are concerned myelography and myelo-CT are necessary. Both myelography and myelo-CT showed high sensitivity (96%), thus allowing the definition of intra- extra-thecal extension of the tumor, and its relationships with the spinal cord and surrounding structures. Myelo-CT turned out to be extremely useful in myelographic stop: the upper extension of the lesion could be defined in 85% of cases. However, the contribution of myelography and myelo-CT was relatively limited when positive findings were present at CT. The evaluation of the density of the lesions proved to be of limited value since no significant differences could be recognized in different tumors. Finally, a diagnostic protocol is proposed for patients with spinal neurologic symptoms, based upon the clinical level of the lesion.
