Cervical magnetic resonance (MR) imaging showed C3-C7 canal stenosis (Fig. 1).
Postoperative CT scans obtained 18 h after cervical laminoplasty. (A) A sagittal image (bone window). (B) Axial images at the C3, C4, C5, and C6 levels (soft-tissue window). The cervical laminoplasty was done, and there is no sign of a hematoma.

The patient complained of slight neck pain, but computed tomography (CT) of the cervical spine 18 hrs after the operation showed no abnormality, including no hematoma (Fig. 2).
Postoperative CT scans obtained 7 days after cervical laminoplasty demonstrate a huge epidural and intramuscular hematoma compressing the spinal cord. (A) A sagittal image (bone window). (B) Axial images from C3 to C6/7 (soft-tissue window).
