Presentation
Low back pain.
Patient Data









There is a bilateral defect of the pars interarticularis of the vertebral arch at the L2 level.
Increased size of the vertebral canal in sagittal direction at the L2 level, specific finding in spondylolysis.
Discoosteophytic complexes at the L2-S1 levels more prominent at the L3-L4 level, moderate intervertebral foramen stenosis at the L2-L3 level.
Intact spinal cord and meninges.

- increased size of the vertebral canal in sagittal direction at L2 level
Case Discussion
Bilateral spondylolysis is usually seen at the L4-S1 levels. There is a rare localisation on the L2 level with a slight anterolisthesis and associated degenerative change, probably accounting for the patient's low back pain.
