 Cervical spine:The left cerebellar tonsil extends 7 mm below the level of the foramen magnum, and the right 6 mm, consistent with Chiari I malformation. There is minimal morphologic distortion with slight pointing. The cervical cord is normal in signal. A suggestion of cord hyperintense signal posterior to C6 on sagittal T2 technique is not reproduced with sagittal STIR or axial T2 and is thus felt to be artifactual. A small flash of biphasic CSF flow is noted posteriorly at the level of the cerebellar tonsils.There is slight reversal of upper cervical curvature. There are no fractures or subluxations. The marrow signal is benign, including a benign hemangioma within the C6 vertebral body. The cervical cord is normal in signal. The cervicomedullary junction is normal. The cerebellar tonsils are in normal position. The visualized paraspinal contents are unremarkable.C2/3: UnremarkableC3/4: UnremarkableC4/5: Mild posterior osteophyte disc complex causing minimal anterior cord flattening. There is no resulting stenosis.C5/6: Mild posterior osteophyte disc complex causing minimal anterior cord flattening. There is no resulting stenosis.C6/7: UnremarkableC7/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, including a benign hemangioma within the T6 vertebral body. The spinal cord is without focal atrophy, signal abnormality, or myelomalacia. There are no masses. Incidental note is made of a right pulmonary azygos lobe.T1/2 demonstrates a tiny left paramedian disc protrusion without 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.
