 5mm grade 1 anterolisthesis of the L4 over L5 vertebral body. No definite evidence of pars defect or acute fracture. The conus is normal in signal and morphology and terminates at L1. Right mid kidney rounded T2 hyperintense structure, most likely a small cyst L1/2: No evidence of significant neuroforamina or central canal stenosis.L2/3: No evidence of significant neuroforamina or central canal stenosis.L3/4: Mild loss of disk height with desiccation. Mild disk bulge with right-sided prominence without significant neuroforaminal narrowing. Right facet hypertrophy. No evidence of significant central canal stenosis.L4/5: Moderate loss of disk height with desiccation. There is uncovering of the disk with mild superimposed disk bulge with moderate bilateral neuroforaminal narrowing. There is thickening of the ligamentum flavum with bilateral facet hypertrophy. There is moderate central canal stenosis. L5/S1: Disk desiccation without loss of height. Mild central to left foraminal protrusion of the disk with abutment of the descending left S1 nerve root. There is also a left foraminal annular fissure. No significant neuroforamina or central canal stenosis.SI Joints: No significant abnormality.
