Low back pain and hip pain. Sciatica, right side. For the purposes of numbering, there are 4 lumbar type vertebral bodies and a fifth transitional segment labeled S1 for the purposes of this study. As such the most inferior well-defined disc space is labeled L4-S1. Vertebral body heights are within normal limits. Alignment is within normal limits. No marrow infiltrating or destructive osseous lesions. T1 hyperintense focus involving the left aspect of S1 is compatible with hemangioma. Small nonspecific sclerotic focus involving the right iliac bone also present on prior CT 5/13/2016. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: Minimal disc bulge with small left extraforaminal disc protrusion. No spinal canal or neural foraminal stenosis.L3-L4: Minimal disc bulge. No spinal canal or neural foraminal stenosis. Mild facet arthropathy.L4-S1: Disc desiccation and minimal bulge. No spinal canal or neural foraminal stenosis. Mild facet arthropathy.Small sacral perineural cysts incidentally noted. Paraspinous soft tissues are within normal limits.
1. Mild degenerative changes in the lumbar spine without significant spinal canal or neural foraminal stenosis at any level.2. Note transitional anatomy with 4 lumbar type vertebral bodies.
