Forgot to mention the summary:

1. Degenerative changes as above, most significant @ L3-L4 and of the neural foramen @ L5-S1.

2. Postoperative change.

3. Lack of contrast limits evaluation for scar.


Also had a pelvis MRI that shows:

Degenerative changes of the SI joints with increased T2 signal/increased T1 signal noted at the SI joints, especially posteriorly. Soft tissues, muscles, and pelvic contents are normal.
