Chiari decompression with syrinx, follow up in February 2015. There are postoperative findings related to Chiari decompression surgery. There appears to be intact CSF flow across the neo-foramen magnum. The discontinuous syrinx that extends from C4-C5 through L1-L2 is stable to perhaps slightly smaller in caliber, measuring up to 6 mm at the midthoracic level. The vertebral column alignment is unchanged. 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 unchanged.
