ABSTRACT
Tumors compromising the neural transmission at the spinal cord can originate in the bone structures or tissue extensions involving the spinal cord and in the neural structures existing inside the bone framework. An accurate diagnosis is crucial to determine the prognosis and direct therapy. Magnetic resonance imaging has revolutionized the diagnosis of intraspinal tumors, allowing for early detection and improved anatomic localization. The clinical findings are mainly a consequence of compression and depend on its localization. The usual complaint is pain and some enervation impairment of the corresponding area. Thoracic tumors cause spasticity and sensorial problems due to involvement of the posterior portion of the medulla and thalamo-spinal tracts. Lumbar tumors promote pain in the posterior areas of the thighs and feet, simulating radicular pain. Neoplastic cells reach the spine through the arterial or venous hematogenic pathway or through direct extension.
