Status post C6-C7 ACDF 8/18 There are postsurgical changes of anterior cervical discectomy and fusion from C6 to C7. Anterior plate and screws are noted which can be better evaluated with CT or radiographs if clinically indicated. There is mild edema involving the vertebral bodies consistent with recent surgery. Previously seen disc extrusion at the C6-C7 level is no longer present. There is minimal effacement of the ventral thecal sac at the C5-C6 level related to minimal disc bulge. Mild degenerative changes also include ligamentum flavum thickening, uncovertebral hypertrophy and facet arthropathy at the C5-C6 and C6-C7 levels. There is no significant spinal canal or neural foraminal stenosis at any level in the cervical spine. No abnormal cord signal. Evidence of prior suboccipital decompression for Chiari I malformation. Fourth ventricular stent is in place and appears similar to prior.
1. Interval postsurgical changes of ACDF at C6-C7 with previously seen disc extrusion at this level no longer present. There is no significant spinal canal or neural foraminal stenosis on the current study.2. Postsurgical changes of prior Chiari I decompression and fourth ventricular stent placement.
