 Cervical spine:The right cerebellar tonsil lies 7 mm below the level of the foramen magnum and demonstrates a pointed morphology, unchanged. CSF flow analysis demonstrates a flash of biphasic flow at the level of the cerebellar tonsils, unchanged in extent.Straightening of the cervical spine is likely positional. There are no fractures or subluxations. The marrow signal is benign. The cervical cord is normal in signal. The visualized paraspinal contents are unremarkable.C2/3: Unremarkable and unchangedC3/4: Small midline protrusion slightly indents the anterior cord surface without intrinsic or signal abnormality and no resulting stenosis, unchanged.C4/5: Unremarkable and unchangedC5/6: Unremarkable and unchangedC6/7: Unremarkable and unchangedC7/T1: Unremarkable and unchangedThoracic spine:There is a smooth, physiologic thoracic kyphotic curve. The vertebral body heights and disc spaces are maintained. Marrow signal intensity is benign throughout. The spinal cord has a smooth contour and is without focal atrophy, edema, or myelomalacia. There are no masses.T1/2 demonstrates no significant disc bulge or cord encroachment, unchanged.T2/3 demonstrates no significant disc bulge or cord encroachment, unchanged. T3/4 demonstrates no significant disc bulge or cord encroachment, unchanged. T4/5 demonstrates no significant disc bulge or cord encroachment, unchanged. T5/6 demonstrates no significant disc bulge or cord encroachment, unchanged.T6/7 demonstrates no significant disc bulge or cord encroachment, unchanged. T7/8 demonstrates no significant disc bulge or cord encroachment, unchanged. T8/9 demonstrates no significant disc bulge or cord encroachment, unchanged. T9/10 demonstrates no significant disc bulge or cord encroachment. There is right ligamentum flavum and facet hypertrophy without significant resulting stenosis, unchanged. T10/11 demonstrates no significant disc bulge or cord encroachment. Bilateral ligamentum flavum and facet hypertrophy without significant resulting stenosis, unchanged.T11/12 demonstrates no significant disc bulge or cord encroachment. Slight ligamentum flavum thickening and facet hypertrophy without significant resulting stenosis, unchanged.T12/L1 demonstrates no significant disc bulge or cord encroachment, unchanged.
1.The right cerebellar tonsil lies 7 mm below the level of the foramen magnum and demonstrates a pointed morphology providing MRI evidence of Chiari I formation. CSF flow analysis demonstrates a flash of biphasic flow at the level of the cerebellar tonsils. These findings are stable in appearance.2.There are no MRI findings of syrinx.3.C3/4: Small midline protrusion slightly indents the anterior cord surface without intrinsic or signal abnormality and no resulting stenosis, unchanged.4.Mild degenerative changes of the lower thoracic spine without significant resulting stenosis are stable in appearance.
