Evaluate for Chiari malformation and CSF flow: headache, N/V. Brain: There cerebellar tonsils extend up to 5 mm inferior to the foramen magnum, but display rounded morphology. There is intact CSF flow across the anterior foramen magnum, but perhaps somewhat blunted flow posteriorly. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift . The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.Cervical Spine: The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.
1. Unchanged low-lying cerebellar tonsils. 2. No evidence of cervical spinal cord syrinx.
