Right arm numbness and weakness. History of non-small cell lung cancer. Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate in height. Alignment is maintained. Bone marrow signal is within normal limits. No masses or abnormal enhancement involving the cervical spine.The cervical spinal cord has normal signal characteristics and overall morphology.Minimal 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: No significant compromise to the spinal canal or neural foramina.C5-6: There is a disc bulge with a central disc extrusion component which contacts the ventral aspect of the cord. No cord signal abnormality. Dorsal thecal sac is patent without significant spinal canal stenosis at this level. There is minimal left neural foraminal narrowing. No significant right 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. Mild bilateral facet arthropathy.The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
1. No evidence of metastatic disease in the cervical spine. 2. Mild degenerative changes including small disc extrusion at the C5-C6 level which contacts the ventral aspect of the cord, without evidence of cord impingement or signal abnormality. There is minimal left C5-C6 neural foraminal narrowing, otherwise no significant spinal canal or neural foraminal stenosis at any level.
