Persistent low back pain. History L5-S1 microdiscectomy. There are postoperative findings related to the previous L5-S1 microdiscectomy through a left laminotomy/partial facetectomy. There is mild protrusion of the L5-S1 disc eccentric to the left with mild enhancement along the surgical defect in the disc. There is also mild enhancement in the epidural fat within the left lateral recess at this level surrounding the nerve roots. There is disc desiccation at L5-S1 and to certain extent L2-L3 and L4-L5, with mild disc height loss. There is facet hypertrophy at the L3 through S1 levels. However, there is no significant spinal canal or neural foraminal stenosis. The vertebral column alignment is within normal limits. There are multilevel small intravertebral disc herniations. The vertebral body heights are otherwise preserved. The vertebral bone marrow signal is unremarkable. The spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.
1.There are expected postoperative findings related to the left L5-S1 microdiscectomy with minimal disc protrusion eccentric to the left as well as a small amount of probable granulation tissue and/or scar tissue formation in the surgical bed.2.No significant spinal canal or neural foraminal stenoses at the other lumbar spine levels.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
