(a) Preoperative T2W sagittal MRI: Marked cervical canal stenosis and cord compression from C2-C3 disc to C7-T1 disc level, predominantly contributed by OPLL with the background of cervical spondylosis. (b) Postoperative T2W sagittal MRI: In addition to an adequately decompressed cervical canal, there is increased signal intensity in the cord with edema opposite at the C3, C6, and C7 levels.

The cervical CT and MR scan both documented OPLL extending from C2-C3 to C7-T1 resulting in significant cervical canal stenosis/ cord compression [Figure 1a]. The postoperative MRI documented adequate cord decompression, but new intramedullary cord edema on the T2-weighted image opposite the C3, C6, and C7 levels [Figure 1b].
