62-year-old man with intermittent right leg numbness and weakness in the right L4 or 5 distribution when sitting in a cramped position. There are five lumbar type vertebral bodies present. There is minimal anterolisthesis of L5 on S1 and loss of disc height at this level; otherwise, the vertebral body and disk heights are well-maintained. The conus medullaris terminates at L1. At L4-5, there is bilateral facet joint hypertrophy and ligamentum flavum thickening resulting in mild bilateral neural foraminal narrowing, but no significant compromise to spinal canal. At L5-S1, there is degenerative disc disease with fatty endplate bone marrow signal alterations and mild facet arthropathy resulting in moderate right and severe left neural foraminal narrowing, but no significant compromise to the spinal canal. While the entire kidneys are not included in the field of view, the imaged portions appear extensively replaced with cysts. There is atrophy of the paraspinous muscles.
1.Degenerative disc disease at L5-S1 and mild to moderate bilateral neural foraminal narrowing at L5-5 and moderate right and severe neural foraminal narrowing at L5-S1, but no significant spinal canal stenosis.2.The imaged portions of the kidneys appear replaced with cysts, which may represent polycystic kidney disease or other form or renal disease. Dedicated renal imaging is recommended for further evaluation if outside studies are unavailable for comparison.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
