The conus terminates at L2 in a low position. T1 and T2 hyperintense lesion of the filum extends from the conus at L2 to the S2 level. This lesion completely suppresses on fat suppressing images without contrast enhancement.
T11/T12 to L3/L4: normal.
L4/L5: small right sided disc extrusion results in minimal central canal narrowing but contact of the descending nerve root in the right subarticular recess.
L5/S1: Shallow central disc bulge. Central disc bulge and facet arthropathy but no central canal or neural exit foraminal stenosis.
Conclusion:
Low lying conus (L2) and tethered cord secondary to filum terminale lipoma.
Right L5 nerve root contact from L4/L5 disc extrusion.
