- Postoperative findings of posterior spinal intrapedicular fusion at L2-L3 level. L2-L3 shows moderate nonenhancing bi foraminal broad-based disk bulging contributing to mild-to-moderate right greater than left neural foramina narrowing. Moderate acquired spinal canal stenosis noted due to enhancing peridural fibrosis with asymmetric more focal extrinsic impression on the right lateral ventral thecal sac. Negligible spondylolisthesis of L2 on L3 noted. Non enhancing cystic foci noted along the posterior elements representing small pseudomeningoceles.
- Postoperative fusion and laminectomy noted at L4-L5 levels with osseous fusion anteriorly. Osseous hypertrophy of the posterior elements noted at L4 and L5.
- L5-S1 level shows subtle left central broad-based disk protrusion. Spinal canal and foramina are patent. No gross thecal sac deformity.
