 The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. The imaged spinal cord displays normal signal and morphology with the conus terminating at L1. There is mild enhancement of the cauda equina nerve roots without evidence of epidural abscess.There is mild unchanged T2 hyperintensity and enhancement within the L3-L4 interlaminar space, likely related to prior lumbar punctures. There is minimal disc desiccation and disc bulge at L3-L4 and mild disc desiccation and disc bulge at L4-L5 there is also mild facet arthropathy and mild posterior annular fissure. These findings are unchanged and do not result in significant spinal canal or neural foramen stenosis.
1.Mild cauda equina enhancement compatible with nonspecific arachnoiditis of uncertain etiology. This may be infectious, inflammatory, neoplastic, or post lumbar puncture in nature and is likely related to the brain findings. Imaging of the cervical and thoracic spine may be helpful to exclude lesions in this location.2.Unchanged mild degenerative changes at L3-L4 and L4-L5 without significant spinal canal or neural foramen stenosis.
