42 female with history of lumbar laminectomy for lipomatosis last March, experiencing left lumbar pain and paresthesia Redemonstrated is congenital spinal canal stenosis. The vertebral body heights are preserved. The bone marrow signal is benign. Note is made of bilateral ovarian cysts and a small amount of pelvic fluid. Otherwise the paraspinal soft tissues are unremarkable. Disc desiccation with mild disc height loss is present at L4/5 and L5/S1, unchangedT12/L1: Mild bilateral facet hypertrophy without stenosis, unchanged.L1/2: Mild bilateral facet hypertrophy without stenosis, unchanged.L2/3: Mild bilateral facet hypertrophy without stenosis, unchanged.L3/4: Minimal bilateral facet hypertrophy without stenosis, unchanged.L4/5: Redemonstrated is a central to right paracentral protrusion, superimposed mild disc bulge, and mild bilateral facet hypertrophy. There has been interval left hemilaminectomy with resection of epidural fat and ligamentum flavum thickening resulting in decompression of the central canal. As before, there is no significant neural foraminal stenosis.L5/S1:There is been slight interval progression of a previously demonstrated left paracentral disc protrusion, with further posterior displacement of the left S1 nerve root sheath. There has also been interval left hemilaminectomy with resection of epidural fat, decompressing the central canal. As before there is bilateral mild facet hypertrophy and no significant neural foraminal stenosis.
