Female, 55 years old, with cervicalgia and history of C1 instability. Spinal alignment is anatomic. In particular, no subluxation of C1 relative to the occiput or to C2 is demonstrated. Vertebral body height and morphology are within normal limits. No areas of pathologic marrow replacement or edema are demonstrated.The visualized spinal cord is normal signal intensity and morphology. No epidural abnormalities are suspected. The cerebellar tonsils are mildly ectopic but the criteria for a Chiari I malformation are not met.C2-3: No spinal canal stenosis or neuroforaminal narrowing. C3-4: No spinal canal stenosis or neuroforaminal narrowing. C4-5: No spinal canal stenosis or neuroforaminal narrowing. C5-6: Minimal disc osteophyte formation. No significant spinal canal or foraminal stenosis. C6-7: No spinal canal stenosis or neuroforaminal narrowing. C7-T1: No spinal canal stenosis or neuroforaminal narrowing.
1.No imaging evidence of C1 subluxation is demonstrated.2.No other specific findings are seen to account for the patient's symptoms.
