66-year-old female with spinal stenosis and low back pain. Five lumbar type vertebral bodies are identified. Mild retrolisthesis at L3-4. Lumbar levoscoliosis is present. Vertebral body heights are preserved. Disc space narrowing and associated degenerative endplate changes are present at L2-3 and L3-4; the bone marrow signal is otherwise within normal limits aside from some scattered Schmorl's nodes. The conus tip is at the level of L1-L2 and the visualized thoracic cord demonstrates normal caliber and signal. There is fatty atrophy of the paraspinal muscles but no paraspinal soft tissue mass.Multilevel degenerative changes are seen, as described below:T11-T12: Unremarkable.T12-L1: No central canal or foraminal stenosis.L1-L2: Small left paracentral disc protrusion causing mild left foraminal stenosis. No central or right foraminal stenoses.L2-L3: Moderate posterior disc bulge and bilateral facet hypertrophy. Mild central and right foraminal stenoses. No left foraminal stenosis.L3-L4: Mild retrolisthesis and associated disc uncovering. Diffuse disc bulge with superimposed right foraminal prominence. Prominent dorsal epidural fat. Bilateral facet hypertrophy. Moderate right foraminal narrowing. Mild central and left foraminal narrowing.L4-L5: Bilateral facet hypertrophy and ligamentum flavum thickening, left greater than right. Mild left foraminal narrowing. No central or right foraminal narrowing.L5-S1: Moderate facet hypertrophy without central or foraminal stenoses.Well-circumscribed T2 hyperintense lesion in the spinal canal at the level of S1-S2 is compatible with a Tarlov cyst.
Multilevel degenerative changes as described above. Most notably, there is a diffuse disc bulge with small superimposed right foraminal prominence at L3-L4 which causes moderate right foraminal narrowing.
