 The last well-formed disk space is referred to as L5-S1. There is benign osseous marrow signal. The vertebral body and disk heights are preserved. There is normal alignment of the lumbar spine. The conus shows normal caliber and signal, terminating normally at L1. There is a 1 mm linear focus of high T1 signal intensity within the lumbar thecal sac likely representing a small vessel.T12-L1: No disk herniation or spinal stenosis.L1-2: No disk herniation or spinal stenosis.L2-3: Minimal disk bulge with no spinal stenosis.L3-4: Minimal disk bulge with no spinal stenosis.L4-5: Mild disk bulge with tiny central protrusion and facet arthropathy with no significant central spinal canal or neural foraminal stenosis.L5-S1: Small disk protrusion with no significant central spinal canal or neural foraminal stenosis.Incidentally seen is a small intraosseous pneumatocyst involving the left iliac bone and also seen on prior abdominal CT.
Minimal lumbar degenerative changes without significant spinal canal or neural foraminal stenosis at any level.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
