 The cerebellar tonsils lie 8-9 mm below the level of the foramen magnum and demonstrate a pointed morphology, consistent with Chiari I malformation.Alignment is anatomic. There are no fractures or subluxations. The marrow signal is benign. The cervical and visualized upper thoracic cord are normal in signal without evidence of syrinx. The cervicomedullary junction is normal. The cerebellar tonsils are in normal position. The visualized paraspinal contents are unremarkable.C2/3: UnremarkableC3/4: Minimal posterior osteophyte disc complex without stenosisC4/5: UnremarkableC5/6: Mild posterior osteophyte disc complex and bilateral uncinate hypertrophy. There is mild right neural foraminal and moderate to severe left neural foraminal stenosis.C6/7: UnremarkableC7/T1: Unremarkable. Note is made of partial fusion of the vertebral bodies posteriorly.
