Neck and right upper extremity pain. Evaluate for stenosis. Redemonstrated are postsurgical findings related to an anterior cervical discectomy and fusion from the C5-6 through C6-7 levels. The craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. Alignment is maintained. Bone marrow signal is within normal limits. The cervical spinal cord demonstrates right coronary atrophy with associated T2 hyperintensity posterior to the C6 vertebral body which is unchanged compared to previous MRI indicating myelomalacia.Degenerative changes are seen in the cervical spine as described below:C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: A disc osteophyte complex is noted with uncovertebral hypertrophy and ligamentum flavum thickening. There is resultant mild to moderate right and mild left neuroforaminal stenosis. No central spinal canal stenosis.C4-5: Again seen is a disc osteophyte complex, facet and uncovertebral hypertrophy as well as ligamentum flavum thickening. This results in moderate to severe bilateral neural foraminal stenosis and moderate central spinal canal stenosis.C5-6: Status post discectomy and fusion. Mild to moderate bilateral neural foraminal stenosis is visualized but there is no central spinal canal stenosis.C6-7: Status post discectomy and fusion. No significant neuroforaminal or central canal stenosis.C7-T1: Small disc osteophyte complex is seen with left greater than right facet hypertrophy. However there is no neural foraminal or central canal stenosis.At the T2-T3 level seen on sagittal imaging is a disc protrusion which abuts the cord and encroaches on the right neural foramen. No significant central spinal canal stenosis at this level.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
1.Postsurgical changes from a C5-C7 anterior cervical discectomy and fusion.2.Multilevel degenerative changes most severe at C4-5 where there is moderate to severe bilateral neuroforaminal stenosis and moderate central spinal canal stenosis.3.The cervical spinal cord demonstrates right coronary atrophy with associated T2 hyperintensity posterior to the C6 vertebral body which is unchanged compared to previous MRI indicating myelomalacia.
