 Postsurgical changes of laminoplasty from C3 to C6. There is minimal retrolisthesis at C4-C5 and C5-C6 and anterolisthesis at C7-T1. Vertebral body heights are intact. There is multilevel disc desiccation with mild multilevel disc space loss. Moderate disc space loss at C6-C7. Endplate degenerative changes at C4-C5 and C7-T1. Mild increased signal within the cord at C4-C5 where there is thinning, suggesting myelomalacia. No abnormal enhancement.C2-C3: Uncovertebral joint hypertrophy. Mild left neural foraminal stenosis. No right neural foraminal stenosis. No spinal canal stenosis.C3-C4: Minimal uncovertebral joint hypertrophy. Moderate left and mild right neural foraminal stenosis. Mild effacement of the ventral and dorsal thecal sac.C4-C5: Uncovertebral joint hypertrophy. Mild effacement of the ventral and dorsal thecal sac. Severe right neuroforaminal stenosis. Moderate to severe left neural foraminal stenosis. C5-C6: Posterior disc osteophyte complex, asymmetric to the right, and uncovertebral joint hypertrophy. Moderate spinal canal stenosis with effacement of the ventral thecal sac and mild indentation of the ventral cord. Severe right neural foraminal stenosis. Moderate to severe left neural foraminal stenosis.C6-C7: Mild uncovertebral joint hypertrophy. No spinal canal stenosis. Mild to moderate right and mild left neural foraminal stenosis.C7-T1: Posterior disc osteophyte complex and uncovertebral joint hypertrophy. Mild effacement of the ventral thecal sac. Moderate bilateral neural foraminal stenosis, left greater than right.There is subtle increased T2 signal within the proximal C7 and C8 nerves on the right, presumably related to proximal impingement. Otherwise, no avulsions or abnormal enhancement is noted throughout the brachial plexus. No masses are seen within the course of the brachial plexus.
1.Evidence of prior laminoplasty with myelomalacia within the cord at C4-C5, presumably related to prior compressive myelopathy.2.Up to moderate spinal canal stenosis at C5-C6 and multiple levels of neural foraminal narrowing, including severe right neural foraminal stenosis at C4-C5 and C5-C6 which may be impinging on the exiting right C5 and C6 nerve roots. There is foraminal stenosis to a lesser degree at C6-C7 and C7-T1 as well.3.Subtle increased T2 signal within the C7 and C8 nerve roots on the right, presumably related to proximal impingement at the neural foramina. Brachial plexus exam is otherwise unremarkable.
