 Cervical spine:6-7 mm cerebellar ectopia is noted with the left demonstrate normal rounded morphology and the right a minimally pointed morphology. Biphasic CSF flow is noted at the level of the cerebellar tonsils.The odontoid tip is mildly retroflexed.Alignment is anatomic. 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: UnremarkableC3/4: Minimal disc bulge without significant mass effect or resulting stenosis. There is focal right uncinate hypertrophy without significant mass effect on the adjacent neural foramen.C4/5: Minimal disc bulge without significant mass effect or resulting stenosis.C5/6: Mild disc bulge and right uncinate hypertrophy without significant mass effect or resulting stenosis.C6/7: Mild disc bulge and right uncinate hypertrophy without significant mass effect or resulting stenosis.C7/T1: UnremarkableThoracic 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.T2/3 demonstrates no significant disc bulge or cord encroachment. T3/4 demonstrates no significant disc bulge or cord encroachment. T4/5 demonstrates no significant disc bulge or cord encroachment. T5/6 demonstrates no significant disc bulge or cord encroachment.T6/7 demonstrates no significant disc bulge or cord encroachment. T7/8 demonstrates no significant disc bulge or cord encroachment. T8/9 demonstrates no significant disc bulge or cord encroachment. T9/10 demonstrates no significant disc bulge or cord encroachment.T10/11 demonstrates no significant disc bulge or cord encroachment. T11/12 demonstrates no significant disc bulge or cord encroachment. T12/L1 demonstrates no significant disc bulge or cord encroachment.
1.MRI evidence for acute Chiari malformation as described in detail above.. Biphasic CSF flow is noted at the level of the cerebellar tonsils.2.No spinal cord syrinx.3.Mild degenerative changes without significant resulting stenosis.
