Right lower extremity weakness and radiating pain. Evaluate nerve root and for lumbar stenosis. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is mild straightening of the lumbar spinal curvature. Alignment is otherwise within normal limits. Bone marrow signal is heterogeneous which is nonspecific but without discrete suspicious osseous lesions. The conus medullaris is normal in position. No abnormal enhancement. Small sacral perineural cyst incidentally noted at the right S2 level. Individual levels described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: Small dorsal annular fissure. Otherwise no significant disc disease. No spinal canal or neural foraminal stenosis.L5-S1: Disc desiccation with small dorsal annular fissure and trace bulge eccentric to the right. There is minimal contact of the right S1 nerve root with the disc without clear evidence of impingement. No central canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits. Multiple bilateral renal cysts are partially imaged.
Minimal degenerative changes in the lumbar spine as described above. There is minimal contact of the right S1 nerve root related to trace disc bulge at the L5-S1 level without obvious impingement. There is otherwise no significant spinal canal or neural foraminal stenosis at any level. No abnormal enhancement.
