Paresthesias, evaluate for demyelinating disease.. Brain: There are approximately 10 T2/FLAIR hyperintense lesions in the bilateral periventricular and subcortical white matter. While some of these foci are nonspecific, morphology and distribution of several of the lesions is suggestive of chronic demyelinating disease. The current study is of higher resolution and previously seen lesions are better appreciated. No new lesion is definitively appreciated to suggest progression of demyelinating disease since 10/24/2014. No infratentorial lesions are definitively appreciated. No significant burden of T1 hypointense lesions. Brain parenchymal volume is preserved.No intracranial mass or mass effect. Ventricles and sulci are normal. No extra-axial collections. Bone marrow signal and extra soft tissues are grossly unremarkable.Cervical spine: Focus of T2 signal abnormality involving the right dorsal aspect of the cord at the right C2 level is again seen. No additional lesions in the cervical cord are appreciated. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. Minimal spondylotic changes are present including tiny disc protrusion at the C5-C6 level. There is no spinal canal or foraminal stenosis within the cervical spine at any level. The paravertebral soft tissues are unremarkable.
1. Multiple, approximately 10, supratentorial white matter lesions are not significantly changed since 10/24/2014 allowing for differences in technique. The distribution and morphology of several of the lesions is suggestive of chronic demyelinating disease.2. Unchanged T2 hyperintense lesion in the right dorsal cervical cord at the C2 level is compatible with a chronic demyelinating plaque. No new lesions in the cervical cord are appreciated.
