Figure 3: Preoperative sagittal (a) and axial (c) T2-weighted MRI reveals a disc herniation at the level of C5-C6 level. Below the same level, the spinal cord had become swollen and hyperintense relative to normal cord tissue. It enhances on T1-weighted scans (b and d) after IV contrast material administration. MRI = Magnetic resonance imaging, IV = Intravenous
