Hemorrhage is common.Īstrocytoma: Frequently located eccentrically in the posterior columns and extends over multiple segments. This tumor usually presents as a well-circumscribed lesion with focal, intense enhancement. Concomitant intracranial lesions in periventricular, subcallosal, brainstem, or cerebellar white matter are usually present.Įpendymoma: Originates from the ependymal walls, being more centromedullary located compared with astrocytomas. The presence of enhancement appears to correlate with active disease. These plaques are less than two vertebral body heights in size, and occupy less than half the cross-sectional diameter of the cord. DWI demonstrates restricted diffusion.ĭemyelinating Disease (Multiple Sclerosis): Usually presents as multifocal plaques that are characteristically located peripherally within the white matter. Usually, infarcts occur in the anterior aspect of the spinal cord, sparing the posterior columns.
