MRI of the Lumbar Spine 4/23/2013:Clinical Indication: Remote microdiscectomy in 2006. Recent redevelopment of bilateral lower extremity pain associated with numbness and paresthesia.
Siemens Espree 1.5 Tesla
Sequences: Coronal PD; sagittal T1, T2 and STIR; axial T2.
Comparison: March 30, 2011
Findings:
Redemonstrated is the grade 1 anterior displacement of L5 on S1. The lumbar vertebral body heights are maintained. Degenerative marrow changes at redemonstrated opposite the L3-L4 and L5-S1 disc spaces.
The L1-L2 and L2-L3 disc spaces remain normal.
L3-L4: Redemonstrated is the right hemilaminectomy and partial right facetectomy. The central canal remains widely decompressed. Normal neural foramina bilaterally.
L4-L5: There is mild posterior annular bulging without canal or foraminal stenosis.
L5-S-1: The bilateral pars interarticularis detects are redemonstrated. There is stable mild posterior annualar bulging. There reminas mild to moderate narrowing of both neural foramina.
Normal conus medullaris. Normal paravertebral soft tissues.
Conclusion:
1. Overall, no significant change from the March 2011 exam.
2. Stable post-operative changes at the L3-L4 level without residual or recurrent canal or neural foraminal stenosis.
3. Stable degenerative disc bulging at L4-L5.
4. Stable grade 1 isthmic spondylolisthesis of L5 on S1 with stable mild to moderate bilateral neural foraminal narrowing.
