Differential signs in the diagnosis of constrictive myelopathy and spinal neoplasms in the thoracolumbar region

Neoplasms of the spinal column and spinal cord, depending on their localization relative to the spinal cord and its membranes, are classified into extradural, intradural extramedullary and intramedullary. Extradural tumors are located outside the dura mater. This category includes tumors of the vertebral bodies and tumors lying in the extradural space of the spinal canal. Intradural extramedullary tumors are found within the dura but outside the spinal parenchyma. Intramedullary tumors originate within the spinal cord and are the rarest group of spinal tumors. The aim of the study is to determine the criteria for the differential diagnosis of studied pathology.
