Prolapsed thoracic intervertebral disc: the importance of CT assisted myelography.
We present six new cases of prolapsed thoracic intervertebral disc (PTIVD), and review the clinical and radiological features, particularly with regard to the role of computed tomography (CT) examination in the diagnosis and management. In patients with atypical lower limb pain, particularly when associated with sphincter disturbances, lumbar myelography is incomplete unless supplemented by an examination of the conus region and lower thoracic cord. The supplementary use of CT in suspected PTIVD is of considerable value to the surgeon in determining the size, position, and volume of the sequestration, and the extent of excavation of the spinal cord by prolapsed disc material.
