Anesthesia of skin [R20.0], Reason for Study: ^Reason: eval plaques / other lesions History: R hand numbness, previous transverse myelitis Brain MRIThere is no evidence of acute ischemic or hemorrhagic lesion.There are multifocal FLAIR/T2 high signal intensity lesions on bilateral periventricular white matter and deep white matter including left frontal white matter lesion. Grossly unchanged since prior scan. There is no evidence of abnormal enhancement.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.C-Spine MRI Post laminectomy status are seen from C4 to C5.Previously seen operation site extradural fluid collections are not seen anymore.However, there are focal T2/STIR increased signal intensity at the level of C2 level just below the foramen magnum level. The lesion is mainly located on the right side but reaches to the midline. Comparing to prior cervical spine MRI, this is a new lesion.There is relatively well circumscribed T2/STIR high signal intensity lesion at the C4 level cervical spinal cord posterior column area which indicate postoperative (cervical spinal cord biopsy) changes. There is subtle T2 high signal intensities on the posterior right lateral aspect of the C5 level (series 1601, image 24/45). This lesion is also new lesion comparing to prior scan (Apr 11/2014).  There is subtle kyphotic angulation of cervical spine at the level of C56. Vertebral body heights are normal.
1. Interval development of new T2/STIR high signal intensity cervical spinal cord lesions at the level of C2 and possibly C5 level as described above.2. Unchanged FLAIR/T2 high signal intensity periventricular white matter and deep white matter lesion.3. No evidence of acute ischemic or hemorrhagic lesion.
