(a) Sagittal T2-weighted magnetic resonance image (MRI) showing a disc bulge (white arrows) at the levels of L3/4 and L4/5. (b) Axial T2-weighted MRI of the segment L3/4 showing a disc bulge (dashed line) with consecutive left-sided lateral recess stenosis and a slight facet joint effusion on the left side (arrowheads).
