Left lumbar radiculopathy. 5 lumbar-type, ribless vertebrae are present. Alignment is anatomic. The vertebral bodies are preserved in height and there is no suspicious marrow lesion. Fat-containing lesion in the L3 vertebral body is unchanged, compatible with a hemangioma. Disc heights are preserved. Multilevel disc desiccation is unchanged to minimally increased since the prior examination. There is no significant compromise to the spinal canal. The tip of the conus medullaris lies at the L1-L2 level. The conus medullaris shows normal signal characteristics and shape as well as the caudal imaged part of the spinal cord.T9-T10 through T11-T12 levels are included only on sagittal imaging but there is no significant spinal canal stenosis.T12-L1: No significant disc herniation. No spinal canal or neural foraminal stenosis.L1-L2 and L2-L3: There is minimal disc bulging but no significant disc herniation and only mild ligamenta flava thickening. There is no significant compromise to the spinal canal or the neural foramina.L3-L4: There is very minimal disc bulge with left paracentral prominence but no significant spinal canal, subarticular recess or neural foraminal stenosis. There is mild facet arthropathy and ligamenta flava thickening.L4-L5: There is eccentric to the left disc bulge which narrows the left subarticular recess. There is moderate facet arthropathy, contributing to mild-to-moderate right neural foraminal stenosis. These findings are unchanged since the prior examination.L5-S1: Minimal disc bulge is unchanged. Moderate left more than right facet arthropathy is also unchanged. No significant spinal canal and only mild bilateral neural foraminal stenoses.
Multilevel degenerative lumbar spondylosis is not significantly changed since January 2014 and results in no significant spinal canal or neural foraminal stenosis other than mild encroachment on the left subarticular recess and right neural foramen at L4-5. Please correlate with left L5 and right L4 radiculopathy. Lower lumbar moderate facet arthropathy is also unchanged.
