Right arm numbness and tingling, dexterity issues with right arm Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate height. Alignment is maintained. Bone marrow signal is within normal limits. The cervical spinal cord has normal signal characteristics and overall morphology.There is congenital narrowing of the cervical spinal canal with superimposed degenerative changes, as described below: C2-3: No significant compromise to the spinal canal or neural foramina.C3-4: Minimal disc bulge and uncovertebral hypertrophy on the right. No significant spinal canal stenosis. There is minimal right neural foraminal narrowing. No significant left neural foraminal narrowing.C4-5: Minimal disc bulge. No significant spinal canal or neural foraminal stenosis.C5-6: There is a right central disc extrusion which mildly indents the ventral cord. There is also uncovertebral hypertrophy with moderate right neural foraminal stenosis and mild left neural foraminal narrowing. There is low T2 signal extending from C5-C6 to C6-C7 along the posterior longitudinal ligament which is likely related to subligamentous disc extrusion.C6-7: There is central disc extrusion which indents the ventral cord. There is no significant neural foraminal stenosis.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.
1. There are disc extrusions at the C5-C6 and C6-C7 levels which indent the ventral cord. There is also low T2 signal extending from C5-C6 to C6-C7 along the posterior longitudinal ligament which is likely related to subligamentous disc extrusion originating from either of the 2 levels. No cord signal abnormality.2. Moderate right C5-C6 neural foraminal stenosis related to disc extrusion and mild uncovertebral hypertrophy. There may be associated impingement of the right C6 nerve root.
