Yearly follow-up of swan-neck deformity, Ehler- Danlos syndrome Craniovertebral junction appears within normal limits. The cervical vertebral bodies are appropriate height. There is reversal of cervical lordosis centered at the C5-C6 level which straightens in the extension position. Bone marrow signal is within normal limits. 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: Minimal disc bulge. No significant compromise to the spinal canal or neural foramina.C4-5: Minimal disc bulge and disc desiccation. No significant compromise to the spinal canal or neural foramina.C5-6: There is partial effacement of the ventral thecal sac related to the reversal of cervical lordosis and minimal bulge. Disc desiccation. No significant compromise to the spinal canal or neural foramina.C6-7: Minimal disc bulge and disc desiccation. 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.
1. No significant spinal canal stenosis or neural foraminal stenosis at any level in the cervical spine. No cord signal abnormality.2. Kyphotic angulation at the C5-6 level, which straightens in the extension position, is unchanged.
