Reason: Eval for demyelinating disease History: paresthesias Cervical spine:The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. There is multilevel disk desiccation present.At C2-3 there is no significant compromise to the neural foramina. There is a central disk extrusion present at this level which is stable compared to the previous exam. It effaces spinal fluid ventral but not posterior to the spinal cord and creates a mild degree of spinal stenosisAt C3-4 there is no significant compromise to the spinal canal or neural foramina. There are some mild degenerative changes present at this level.At C4-5 there is no significant compromise to the spinal canal or neural foramina.At C5-6 there is no significant compromise to the spinal canal or neural foramina.At C6-7 there is no significant compromise to the spinal canal or neural foramina.At C7-T1 there is no significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact. The left vertebral artery is larger than the right vertebral artery.MRI thoracic spine:There is abnormal spinal cord signal present from T3 through T6 centered in the left hemicord posteriorly. There is no associated enlargement of the spinal cord .The thoracic vertebral bodies are appropriate in the overall alignment and height. There is no compromise of thoracic spinal canal or exiting nerve roots. Lumbar spine:Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The conus medullaris on sagittal imaging is grossly intact.At L5-S1 there is no significant compromise to spinal canal or neural foramina.At L4-5 there is a broad-based left lateral recess disk protrusion which partially effaces the fat of the left lateral recess.At L3-4 there is loss of disk space height, disk desiccation and a diffuse disk bulge associated with partial effacement of the fat of the lateral recesses left more than right.At L2-3 there is no significant compromise to spinal canal or neural foramina.At L1-2 there is no significant compromise to spinal canal or neural foramina.
1.There is a large C2-3 disk extrusion present which is stable compared to the prior exam. It creates a mild degree of spinal stenosis. It is unchanged since 6/12/142.there is a spinal cord lesion extending from T3 through T6 which appears relatively stable when compared to the previous exam. One possibility is that this is related to demyelination. Please correlate with clinical exam findings. It is unchanged since 6/12/14.3.there are disk protrusions present in the lumbar spine with some mild encroachment of the nerve roots at the left lateral recess at L4-5 and L3-4.
