Low back pain for 4 to 6 weeks with arching and in school, plays volleyball, has spina bifida occulta S1. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position. No evidence of filar lipoma or other lesions within the spinal canal. Incomplete posterior arch of S1 is incidentally noted and is a common developmental variant.Individual levels as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: No significant disc disease. No spinal canal or neural foraminal stenosis. L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis. There are findings suggestive of mild facet arthropathy at L4-L5 and L5-S1. Paraspinous soft tissues are within normal limits.
1. No significant disc disease or spinal canal or neural foraminal stenosis at any level.2. No evidence of tethered cord, filar lipoma, or other lesions within the spinal canal.3. If there is specific suspicion for a pars fracture, oblique radiographs or CT would be helpful. There is however no evidence of spondylolisthesis or edema involving the posterior elements.4. There is mild facet arthropathy at L4-L5 and L5-S1.
