Chiari malformation decompression with syrinx, 3 month post op follow up. There are interval postoperative findings related to Chiari decompression surgery, with a intact cerebrospinal fluid flow across a widened neo-foramen magnum and decreased size of the long-segment cervicothoracic syrinx, which measures up to 5 mm in width, previously 7 mm. There is no evidence of pseudomeningocele. The vertebral column alignment is within normal limits, aside from a mildly retroflexed dens. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis.
