Cervical stenosis Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. Alignment is maintained. Bone marrow signal is within normal limits. Again seen is a disc extrusion at the C4-C5 level which appears minimally larger than prior and is associated with deformity of the ventral cord. Subtle T2 hyperintensity is suspected in the cord at this level. The remainder of the cervical spinal cord has normal signal characteristics and overall morphology.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: No significant compromise to the spinal canal or neural foramina.C4-5: Right central disc extrusion which appears minimally larger than prior study. No significant right neural foraminal narrowing. There is mild left neural foraminal narrowing related to uncovertebral hypertrophy and facet arthropathy. C5-6: Small disc osteophyte complex and ligamentum flavum thickening contributing to mild spinal canal narrowing. There is mild right-sided neural foraminal narrowing related to uncovertebral hypertrophy. No significant left neural foraminal narrowing. C6-7: No significant compromise to the spinal canal or neural foramina.C7-T1: No significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
Compared to 4/22/2014 there is minimal interval increase in size of disc extrusion at the C4-C5 level which deforms the ventral cord at this level. Subtle T2 hyperintensity in the cord is suspected at this level. Mild degenerative changes at additional levels as detailed above.
