Leg weakness and heaviness. Lumbar radicular pain, multiple joint AVN, high titers APS Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits aside from straightening. Bone marrow signal is benign. The conus medullaris is normal in position.There is developmental narrowing of the lumbar spinal canal without high-grade spinal canal stenosis at any level. No significant disc disease is present from T12-L1 to L4-L5. At L5-S1, there is disc desiccation as well as a central disc protrusion which partially effaces the lateral recesses without significant central spinal canal stenosis. There is fairly mild neural foraminal narrowing at this level, relatively greater on the left. There is also mild generalized facet hypertrophy throughout the lumbar spine.Paraspinous soft tissues demonstrate prominence of the subcutaneous fat but are otherwise unremarkable. There is a cyst in the right kidney.
1. Development of narrowing of the lumbar spinal canal without high-grade spinal canal stenosis or neural foraminal stenosis at any level.2. There is a central disc protrusion at the L5-S1 level with partial effacement of the lateral recesses and mild neural foraminal narrowing at this level.
