Clinical question: Chiari malformation, decompression, syrinx, yearly follow-up, evaluate for change. Signs and symptoms: Neck pain and spasm post surgery. Nonenhanced cervical MRI:Examination demonstrates stable expected postoperative changes of Chiari decompression without change since prior exam.A minimally expansile syrinx of cervical cord extending from C2 to C7 demonstrate no convincing evidence of change in its size or extent. Signal intensity and the alignment of the vertebral column is unremarkable. There is no spinal stenosis or neural foraminal compromise at any level.
1.No evidence of an acute or new findings since prior study.2.Stable postoperative changes of Chiari decompression with expansion of subarachnoid space.3.Stable minimally expansile single cervical cord from C2 to C7 since prior study.
