81 years Male (DOB:12/10/1934)Reason: evaluate for structural abnormalities History: progressive weakness of L arm and L leg, atrophy, fasciculations, gait abnormality PROVIDER/ATTENDING NAME: THOMAS J KELLY THOMAS J KELLY MRI thoracic spine:The thoracic vertebral bodies are appropriate in the overall alignment and height. The thoracic spinal cord has normal signal characteristics and overall morphology. There is no compromise of thoracic spinal canal or exiting nerve roots. No abnormal enhancing lesions are appreciated in the thoracic spine.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.No abnormal enhancing lesions are appreciated in the lumbar spine.At L5-S1 there is moderate to marked bilateral facet and ligamentum flavum hypertrophy present at this level associated with the mild diffuse disc bulge. There is effacement of the fat at the lateral recesses bilaterally at this level. There is mild encroachment of the exiting nerve roots within the neural foramina at this level.At L4-5 there is moderate bilateral facet hypertrophy at this level associated with some ligamentum flavum hypertrophy. There is a diffuse disc bulge at this level. There is effacement of the fat at the lateral recess at this level. There is crowding of the nerve roots within the thecal sac at this level. Overall there is a moderate degree of spinal stenosis at this level. Although the neural foraminal are narrowed, within the neural foramina the exiting nerve roots are surrounded by fat.At L3-4 there is no significant compromise to spinal canal or neural foramina.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.There are couple subcentimeter cysts in the left kidney.
1.There is a moderate degree of spinal stenosis at L5-S1 and L4-5 due to facet hypertrophy and a disc bulge.2.No spinal cord lesions are appreciated to explain the patient's symptoms
