Figure 1. Lumbar spinal MRI of the patient demonstrating the L4-L5 discal cyst, with prominent compression of the left L5 nerve root. (a) Sagittal T1-weighted image shows an ovoid lesion with low signal intensity (red arrow). (b) Sagittal T2-weighted image shows an ovoid lesion with a hyperintense center plus hypointense rim (red arrow). (c) Axial MRI shows the lesion (red arrow). (d) Lumbar T2-weighted MRI shows no residual cyst. MRI: magnetic resonance imaging.
