46 your female with lower back pain. The bony density and vertebral alignment are normal. No central spinal stenosis is apparent on exam. The neural foramen are widely patent. L3/4, L4/5, L5/S1 show minimal disk disease, minimal hypertrophy of the posterior elements, and overall minimal degenerative changes. In the last image of the study at S2, there is expansion of the thecal sac without epidural fat. This is of CSF density and may represent an ectatic thecal sac versus a Tarlov cyst. MRI may further evaluate if indicated.
