Increased headaches and previous possible history of syrinx. Brain: There cerebellar tonsils display a normal morphology and are not low-lying. There is intact CSF flow across the foramen magnum. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is mild asymmetry of the lateral ventricles, which can represent an anatomic variant. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is scattered paranasal sinus mucosal thickening.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. No evidence of Chiari malformation or cervical spinal cord syrinx.2. Scattered paranasal sinus mucosal thickening may indicate sinusitis.
