Case Report

HISTORY: Lumbosacral pain radiating down both extremities.

TECHNIQUE:
Outside MR images of the lumbar spine from American Radiology dated 10/8/2011 were submitted for second opinion consultation on 11/29/2011.
Sagittal T1, T2, STIR, and axial T1 and T2-weighted images of the lumbar spine were obtained without intravenous contrast.

COMPARISON: None.

FINDINGS:
Vertebral body height and alignment are within normal limits. Marrow signal is normal with no evidence of a fracture or a marrow infiltrating lesion. Intervertebral discs are well hydrated. No significant degenerative changes are seen, and the central canal and neuroforaminaare widely patent throughout the lumbar spine. The conus is normal in appearance and terminates at the L1-L2 level. The cauda equina roots demonstrate no evidence of clumping to suggest arachnoiditis. Fat is seen along the filum terminale on the axial T1-weighted images. There is no spinal dysraphism. Visualized intra-abdominal structures are unremarkable.

IMPRESSION:
Fatty filum terminale. No evidence of spinal dysraphism. Conus terminates normally at the L1-L2 level.
