For the purposes of numbering on this examination, 5 lumbar-type vertebral bodies are assumed, with the lowest well-formed disc space designated L5-S1. Utilizing this numbering system, the conus terminates at the approximate level of L1-L2. The limited visualized cord appears unremarkable in signal. Lumbar lordosis grossly maintained. There is slight loss of disc height posteriorly at L4-L5, with disc desiccation also noted at L4-L5. Disc height and disc signal elsewhere within the lumbar spine otherwise appear fairly well-preserved. Marrow signal intensity appears grossly appropriate.
T12-L1: Minimal posterior disc bulge. No evidence for central canal stenosis. Ligamentum flavum hypertrophy noted. Neural foramina appear grossly patent.
L1-L2: Posterior disc bulge effacing the ventral subarachnoid space. No evidence for central canal stenosis. Ligamentum flavum hypertrophy and mild facet hypertrophy are noted. Neural foramina appear grossly patent.
L2-L3: Posterior disc bulge effacing the ventral subarachnoid space. No evidence for central canal stenosis. Ligamentum flavum hypertrophy and mild to moderate facet hypertrophy are noted. Mild bilateral neural foraminal stenosis.
L3-L4: Posterior disc bulge effacing the ventral subarachnoid space. No evidence for central canal stenosis. Ligamentum flavum hypertrophy and moderate facet hypertrophy noted. Tiny synovial cyst noted adjacent to the articular facets. Mild right and mild to moderate left neural foraminal stenosis.
L4-L5: Posterior disc bulge effacing the ventral subarachnoid space. No evidence for central canal stenosis. Narrowing of lateral recesses noted. Ligamentum flavum hypertrophy and severe facet hypertrophy. Synovial cyst noted adjacent to the articular facets. Moderate bilateral neural foraminal stenosis.
L5-S1: Posterior disc bulge effacing the ventral subarachnoid space. No evidence for central canal stenosis. Ligamentum flavum hypertrophy and severe facet hypertrophy noted. Synovial cyst noted adjacent to the articular facets. Mild to moderate bilateral neural foraminal stenosis.
There is no evidence for abdominal aortic aneurysm.
Impression:
Scattered degenerative changes of the lumbar spine, with facet hypertrophy and neural foraminal stenosis, as detailed above.
