Surgical treatments include removing bone spurs and widening the space between vertebrae. Put simply, a lesion is the name given to an abnormal change which occurs to any tissue or organ, caused by a disease or injury. This pattern is caused by the high-contrast interface of CSF with the spinal cord and can be minimized by increasing the number of phase-encoding steps, switching the frequency- or phase-encoding directions, or decreasing the field of view (3). You mention that there are a number of things that could cause abnormal signal. MeSH What should I do? MRI of the brain as well as the spinal cord is essential and may further help distinguish ADEM from MS. Intracranial findings may mimic MS, but certain features help confirm the diagnosis of ADEM, such as the presence of larger lesions in the subcortical white matter, involvement of the deep gray matter structure (basal ganglia and thalami) and brainstem, and relative sparing of the periventricular region (14,16) (Fig 6). what does this mean?
