l4-5 mid diffuse annular disc bulge indenting thecal sac, abutting bilateral traversing nerve roots and causing bilateral neural foraminal stenosis. A small synovial syst measuring 5.1 mm x 6.7 mm is seen in the left postero-lateral space focally compressing left traversing nerve root. Mild legamentum flavum hypertrophy is seen at this level. My MRI report for spine. What does it talk about ?
