Myelopathy, the rapid or insidious onset of motor and sensory abnormalities referable to the spinal cord, occurs as a result of a variety of causes that may be classified on the basis of their location of origin (intramedullary, intradural-extramedullary, and extradural). The first goal of imaging is to appropriately assign the observed abnormality to its location of origin and, therefore, into the correct diagnostic list. This article focuses on the plain film, computed tomography, and magnetic resonance demonstration of extradural causes of myelopathy.
