Male, 46 years old, with multiple sclerosis presenting with weakness. Evaluate for progression. Brain:Several small scattered foci of T2 hyperintensity are seen within the juxtacortical and periventricular white matter of the cerebral hemispheres. The corpus callosum is also involved. No definite lesions are seen in the brainstem or cerebellum. Since the prior examination, mild rim T2 hyperintensity along the lateral ventricles appears slightly increased, but this could be due to differences in technique. Scattered focal lesions appear grossly unchanged in size and number.No edema or mass effect is observed. No abnormal extra-axial collections are seen. Ventricular size and morphology remain within normal limits. Volume of the brain and corpus callosum remains within normal.Cervical spine:No definite focal cord signal abnormality is seen in the cervical region. No epidural lesions are detected. Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. No marrow replacement is seen. Minimal degenerative findings are evident without significant spinal canal stenosis. Mild foraminal narrowing is seen on the left at C3-4 and on the right at C4-5.Thoracic spine:Very subtle areas of cord T2 signal abnormality are seen for example at T4 centrally and at T6-7 dorsally. Both of these lesions appear less conspicuous than on the prior exam. Prominence of the central canal of the spinal cord is seen spanning from T5 through T8 with very slight prominence continuing more inferiorly. This finding is grossly unchanged from prior.Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. No evidence of marrow replacement is seen. Mild facet edema is seen at T8-9 on the left likely related to joint arthropathy. The intervertebral discs are relatively well preserved with only minimal degenerative changes seen. No significant compromise of the spinal canal is demonstrated. Foraminal narrowing is present bilaterally at T8-9.
1.A relatively small number of scattered T2 hyperintense lesions are seen in the brain compatible with multiple sclerosis. Slight apparent increased conspicuity of rim T2 hyperintensity along the lateral ventricles may be technical. Scattered discrete lesions are unchanged in size and number.2.No definite spinal cord lesions are seen in the cervical region. Two small areas of very mild cord signal abnormality are suspected in the thoracic spine. In both cases, the prior examination showed larger, more conspicuous lesions in these locations.3.Prominence of the central canal of the spinal cord is seen in the mid to lower thoracic spine without significant interval change.
