Findings:
Sacralisation of l5 vertebra. Fused with L5 and S1,
L4-5 diffuse disc bulge with disc desiccation causing anterior thecal sac indentation without significance neural compromise.
AP Spinal Diameter - L1 (1.35), L2(1.35),L3(1.35), L4(1.35), L4-5(0.85) , L5(1.1)
Sacroiliac Joints - appears normal
C4-5 diffuse disc bulge causing anterior thecal sac indentation without significant neural compromise.
Impression:
Altered signal intensity with enhancement noted in the L1 and L3 vertebral body and l1 posterior elements without significant mass lesion - 2/0 secondaries.
L5-S1 diffuse disc bulge causing anterior thecal sac indentation and bilateral neural foramen narrowing without significant nerve root compression.
Grade 1 anterior spondylolisthesis of the L4 over L5 with L4-L5 diffuse disc bulge causing anterior thecal sac indentation and bilateral neural foramen narrowing , abutting the bilateral traversing nerve roots.
