Reason: eval for spondylolysis History: lbp with hockey for months with significant LLD--left sided pain; right leg long Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits. The conus medullaris is normal in position. Bone marrow signal is benign. There appear to be bilateral L5 pars defects with mild fluid along the defect and mild adjacent edema. There is also mild fluid in the L4-L5 and L5-S1 facet joints, left relatively greater than right. Paraspinous soft tissues are otherwise unremarkable.There are minimal disc bulges in the lumbar spine at L4-L5 and L5-S1 with minimal narrowing of the neural foramina. There is no significant spinal canal or neural foraminal stenosis at any level.
Likely bilateral L5 spondylolysis without spondylolisthesis. CT can be considered for optimal visualization of the pars defects. There is small amount of fluid at the site of the pars defects with mild surrounding edema and mild fluid extending into the L4-L5 and L5-S1 facet joints, left relatively greater than right.
