| - FINDINGS: |
| - There is a 20 degrees levoconvex curvature with the apex at the L3 level. This includes 6 mm leftward listhesis of L3 on L4. Vertebral AP alignment in the midline sagittal plane shows minimal 2 mm grade 1 retrolisthesis of L3 on L4 and anterolisthesis of L4 on L5. No spondylolysis is seen with intact pars interarticularis bilaterally at the L3, L4 and L5 levels. Moderate mixed Modic type I and type II discogenic degenerative endplate changes are seen anteriorly at the L2-L3 and L3-L4 levels. The vertebral bone marrow signal intensity is otherwise normal with no indication of neoplastic infiltration or infection. No compression fracture is identified. The pedicles are intact bilaterally with no signs of stress fracture or destructive change. |
| - The conus is normal in size, signal intensity and position with the tip at the L1-L2 level. The cauda equina roots are normally distributed without clumping or peripheral displacement by adhesions. |
| - T12-L1, partially visualized in the sagittal plane only, shows normal disc signal and height without disc bulge or focal protrusion, canal stenosis or neural foramen stenosis. |
| - At L1-2, there is a bilobed disc bulge with 2 mm left paramedian focal protrusion and mild bilateral facet arthropathy with minimal ligamentum flavum folding and small joint space effusions. Mild left lateral recess narrowing without traversing L2 nerve root impingement. No central canal stenosis or right lateral recess narrowing. Mild bilateral neural foramen stenosis. |
| - At L2-3, there is a mild bilobed disc bulge with mild facet arthropathy and ligamentum flavum folding including small joint space effusions. Mild lateral recess narrowing bilaterally with no central canal stenosis. Moderate left and mild right neural foramen stenosis with impingement on the exiting left L2 nerve root.. |
| - At L3-4, there is severe disc desiccation on the right with mild bilateral facet arthropathy and ligamentum flavum folding including small joint space effusions. These changes produce severe right and moderate left lateral recess narrowing with possible compression of the traversing right L4 nerve root. Mild central canal stenosis. Severe right and moderate left neural foramen stenosis with possible compression of the exiting right L3 nerve root. |
| - At L4-5, there is a broad disc bulge eccentric to the left with moderate left and mild right hypertrophic facet arthropathy. Moderate left and mild right ligamentum flavum folding. These changes produce severe left and mild right lateral recess narrowing with mild central canal stenosis. Possible compression of the traversing left L5 nerve root. Severe left and moderate right neural foramen stenosis. Possible compression of the exiting left L4 nerve root. |
| - At L5-S1, there is a mild disc bulge with mild bilateral facet arthropathy including small joint space effusions. No central canal stenosis or lateral recess narrowing. Mild neural foramen stenosis bilaterally.. |
| - Limited evaluation of the prevertebral and paraspinal soft tissues is unremarkable with no lymphadenopathy, mass or infiltrative disease and normal caliber aorta. The partially visualized sacroiliac joints are normal bilaterally. |
| IMPRESSION: | | - Normal vertebral alignment and marrow signal without evidence for spondylolisthesis, marrow infiltration or compression fracture. | | - L1-2, bilobed disc bulge with 2 mm left paramedian focal protrusion. Mild facet arthropathy. Mild left lateral recess narrowing. No central canal stenosis. Mild neural foramen stenosis bilaterally. | | - L2-3, mild bilobed disc bulge with mild facet arthropathy and mild lateral recess narrowing. No central canal stenosis. Moderate left and mild right neural foramen stenosis. | | - L3-4, severe right-sided disc desiccation with mild facet arthropathy. Severe right and moderate left lateral recess narrowing. Mild central canal stenosis. Severe right and moderate left neural foramen stenosis. | | - L4-5, broad disc bulge eccentric to the left with moderate left and mild right facet arthropathy. Severe left and mild right lateral recess narrowing. Mild central canal stenosis. Severe left and moderate right neural foramen stenosis. | - L5-S1, mild disc bulge with mild facet arthropathy. No central canal stenosis or lateral recess narrowing. Mild neural foramen stenosis bilaterally.
my lower back pain is on my left side, yet it creates groin pain on the right.
