Status post Chiari decompression with increasing leg pain/stiffness. Brain: There are postoperative findings related Chiari decompression with improved configuration of inferior cerebellum and CSF flow across the neo-foramen magnum. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is encephalomalacia in the region of the cerebellar tonsil with punctate susceptibility effect, which may be attributable to tonsillectomy. The brain parenchyma otherwise unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. There is mucosal thickening in the maxillary sinuses.Spine: The spinal cord now displays normal signal and morphology, without syringomyelia. 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 paravertebral soft tissues are unremarkable.
1. Postoperative findings related Chiari decompression with improved configuration of inferior cerebellum and CSF flow across the neo-foramen magnum. 2. No evidence of syringohydromyelia.
