Chiari decompression and cervical syrinx with shunt tubing in thoracic cord: right arm pain, upper back and Low back pain, LE pain more left side. There are postoperative findings related to Chiari decompression. There is cerebrospinal fluid flow across the anterior neo-foramen magnum, but deficiency of fluid posteriorly. There is a long-segment cervicothoracic syrinx that measures up to 6 mm in width in the upper cervical spine. There is a syrinx shunt tube in position in the lower cervical spine. There is reversal of the usual cervical lordosis and multilevel degenerative spondylosis, with mild spinal canal stenosis at C4 and C5. There is mild thoracic levoscoliosis, but no significant thoracic spinal canal stenosis. There is slight anterolisthesis of L4 on L5 and degenerative spondylosis in the lower lumbar spine, with moderate spinal canal stenosis and left neural foraminal stenosis at L4-5. The vertebral body heights are preserved. The vertebral bone marrow signal appears to be unremarkable. There are hepatic and right renal cysts.
