71 year-old female experiencing low back pain and difficulty ambulating, left more symmetric than right, history of L5/S1 radiculopathy Limited view of the lower thoracic spine and thoracic cord is unremarkable.T12/L1: Mild bilateral facet hypertrophy without stenosis, unchanged.L1/2: There is a new midline disc extrusion which extends above the disc level superimposed upon asymmetric bulge to the left. There is also ligamentum flavum thickening and mild bilateral facet hypertrophy. There is new mild central central and mild to moderate left lateral recess with stable mild left neural foraminal stenosis.L2/3: Asymmetric bulge to the left, ligamentum flavum thickening, progression of prominent posterior epidural fat, mild left facet hypertrophy, and mild to moderate right facet hypertrophy. There is new mild stenosis and stable mild left neural foraminal stenosis.L3/4: Diffuse annular disc bulge, progression of prominent epidural fat, ligamentum flavum thickening, and moderate bilateral facet hypertrophy. There is new mild to moderate central stenosis as well as stable moderate right neural foraminal and mild left neural foraminal stenosis.L4/5: Diffuse annular disc bulge, progression of prominent epidural fat, ligament of flavum thickening, severe bilateral facet hypertrophy, and a right facet effusion. There is new mild to moderate central stenosis as well as stable mild bilateral lateral recess and moderate bilateral neural foraminal stenosis.L5/S1: Previously demonstrated T1 and T2 hyperintensity of disc material now appears predominantly hypointense on both sequences. There has been interval significant progression of epidural fat, now resulting in severe central stenosis, whereas previously there was none. There remains diffuse annular disc bulge and mild to moderate bilateral facet hypertrophy which result in stable mild to moderate bilateral neural foraminal stenosis.
