Female, 38 years old, back pain with radiation to the right lateral thigh. The alignment is notable for mild straightening which may reflect patient positioning. The vertebrae are of normal morphology and normal marrow signal. The vertebral bodies are preserved in height. Intervertebral discs are notable for mild loss of T2 signal at L4-L5. The heights are preserved. The spinal cord is of normal morphology and signal characteristics. The tip of the conus medullaris is at the upper L2 vertebral level.L1-L2, L2-L3 and L3-L4: There is no significant degenerative change. There is no spinal canal or neural foraminal narrowing.L4-L5: There is a disc bulge, which causes flattening of the anterior aspect of thecal sac (mild spinal canal narrowing). There is also a superimposed right foraminal protrusion component resulting in moderate-to-severe right neural foraminal narrowing. There is mild left neural foraminal narrowing. There is facet arthropathy.L5-S1: There is right worse than left facet arthropathy but there is no spinal or neural foraminal narrowing.
1.A right foraminal L4-L5 disc protrusion causes moderate-to-severe right foraminal narrowing, affecting the right L4 nerve root. Other milder degenerative findings are present at L4-L5 as described above.2.There is no significant spinal canal or foraminal stenosis at the other levels.
