Chiari malformation and surgery, headaches, neck pain, numbness, and tingling both hands and arms: 3 month follow up. Brain: There are stable postoperative findings related to Chiari decompression and fourth ventricular stenting. The cerebellum displays an unchanged morphology and signal characteristics. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits and paranasal sinuses are grossly unremarkable.Spine: There is a posterior disc-osteophyte complex that indents the spinal cord and results in mild bilateral neural foramen stenosis. Otherwise, there is no evidence of spinal cord signal abnormality or syrinx. There is no significant neural foramen stenosis. The vertebral column alignment is within normal limits. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable. The paravertebral soft tissues are unchanged.
1. Stable postoperative findings related to Chiari decompression and fourth ventricular stenting without evidence of syringohydromyelia or ventriculomegaly.2. A posterior disc-osteophyte complex at C6-7 indents the spinal cord and results in mild bilateral neural foramen stenosis.
