Delayed neurological dysfunction following posterior laminectomy with lateral mass screw fixation: A case report and review of literature

Figure 1 Preoperative magnetic resonance imaging image of the cervical spine showing C3-C7 spinal canal stenosis with spinal cord edema. A: Sagittal T2 weighted imaging (T2WI); B: Sagittal T2WI + fat suppression; C and D: Axial T2WI at the C5/6 (C) and C6/7 (D) levels showing traumatic disc rupture, protrusion and spinal cord compression.

Figure 2 Postoperative magnetic resonance imaging obtained 8 h after symptom onset and the intraoperative view. A: Magnetic resonance imaging (MRI) showing heterogeneous intensity on T2 weighted imaging (T2WI); B: MRI showing an isointense low signal intensity on T1WI with marked indentation on the dural sac; C and D: Intraoperative image showing the spinal epidural hematoma.

Figure 3 Postoperative magnetic resonance imaging taken 30 d after epidural hematoma elimination. A: Sagittal T2 weighted imaging (T2WI); B: Sagittal T1WI; C and D: Axial T2WI at the C5/6 (C) and C6/7 (D) levels. Epidural hematoma has completely vanished, and the central spinal cord showed high signal at the level of C4-C5 on T2WI.
