There is straightening of the lumbar spine with grade 1
retrolisthesis of L5 on S1. There are minimal Schmorl's nodes,
but overall vertebral heights are maintained. There is diffuse
loss of T2 disc signal from disc desiccation with loss of height
noted particularly at L5-S1. There are diffuse degenerative
endplate signal changes and osteophytic lipping but predominantly
at the L5-S1 level. The conus tip is located at T12-L1.
At L1-L2 there is mild facet arthropathy and ligamentum flavum
hypertrophy without significant central spinal stenosis or
foraminal narrowing. T2 prolongation posterior to the right facet
is likely a synovial cyst.
At L2-L3 there is trace disc bulge with facet arthropathy
ligamentum flavum hypertrophy with mild indentation of the
ventral thecal sac along with mild foraminal narrowing on the
left.
At L3-L4 there is mild disc bulge with facet arthropathy and
ligamentum flavum hypertrophy with mild indentation of the thecal
sac and trace right and mild-to-moderate left foraminal
narrowing.
At L4-L5 there is bulge with superimposed broad based right
lateral recess/foraminal protrusion with facet arthropathy and
ligamentum flavum hypertrophy with mild central and right lateral
recess narrowing with moderate left and mild right foraminal
narrowing
At L5-S1 there is uncovering of the disc with bulge with facet
arthropathy and ligamentum flavum hypertrophy with mild
indentation of the ventral thecal sac along with mild to moderate
right and mild left foraminal narrowing.
