 There are 5 lumbar-appearing vertebrae. For the purposes of this exam, the last fully formed disc is at L5-S1 with the last rib-bearing vertebra designated as T12.The lumbar spine is in normal alignment, with a normal lumbar lordosis. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. The distal spinal cord and conus are within normal limits with the conus terminating at the low normal L2-L3 level. On prone imaging, there is clear ventral motion of the distal cord and conus within the thecal sac. No abnormal fat signal intensity is seen along the distal thecal sac to suggest a fatty filum.There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the lumbar spine.
Essentially unremarkable noncontrast MRI of the lumbar spine, without MR imaging findings of tethered cord. Conus termination is at the lower limits of normal at L2-L3.
