 There is exaggerated lordosis of the lumbar spine. There is a minimal anterolisthesis of L5 on S1. Otherwise, the alignment of the lumbar spine is within normal limits. The vertebral body heights are preserved. There is no evidence of acute fracture. Bilateral L5 pars defects are present without associated edema, and are chronic. There are no other areas of edema-type signal to suggest a stress reaction. No evidence of spinal canal stenosis or neural foraminal narrowing at any level. The conus is normal in signal and morphology and terminates at L1. The visualized intra-abdominal and paraspinal contents are unremarkable.
1. Chronic bilateral L5 pars defects with minimal anterolisthesis of L5 on S1.2. No evidence of acute fracture, spinal canal stenosis, or neural foraminal narrowing.
