Reason: Evaluate for cause of UE weakness History: RUE weakness, thenar wasting The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology.In general there appears be thickening of the posterior longitudinal ligament which contributes to spinal stenosis.At C2-3 there is narrowing of the AP dimension the spinal canal related to posterior longitudinal ligament thickening and also thickening of the posterior ligaments. Spinal fluid is partially effaced anterior and posterior the spinal cord appeared spinal cord appears atrophic at this level.At C3-4 there is disk desiccation and diffuse disk bulge associated with a new left paramedian disk protrusion and effacement of spinal fluid ventral posterior the spinal cord. Overall there is a mild/moderate degree of spinal stenosis present associated with an atrophic appearance of the spinal cord. There is mild posterior ligament hypertrophy at this level. There are bilateral ritual osteophytes present at this level.At C4-5 there is loss of disk base height disk desiccation, diffuse disk bulge and uncovertebral and to a lesser degree endplate osteophytes. There is effacement of spinal fluid ventral to the spinal cord at this level with a narrowing of the left neural foramen due to disk material and osteophytes. Overall there is moderate spinal stenosis at this level.At C5-6 there is no significant compromise to the spinal canal or neural foramina. There is a disk bulge present at this level associated with some thickening of the posterior longitudinal ligament.At C6-7 there are disk desiccation and disk bulge associated with uncovertebral osteophytes bilaterally and encroachment of the exiting nerve roots within the 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.There are small punctate lesions identified in the visualized portions of the lower cerebellar hemispheres left more than right this appearance is unchanged since the prior MRI of the brain from two days ago.There is medial deviation of the right internal carotid artery at the C3 level into the retropharyngeal area.
1.There are multilevel degenerative changes present in the cervical spine associated with some thickening of the posterior longitudinal ligament. This results in mild/moderate spinal stenosis at C2-3 and C3-4 and moderate spinal stenosis at C4-5 as well as multilevel encroachment of the exiting nerve roots as detailed above.2.Small focus of encephalomalacia is present in the left cerebellar hemisphere
