MRI Study: Lumbar spine.
Clinical Information: Low back pain. Right leg pain.
Technique: 2 MR series (sagittal T2, axial Tl)
Findings: No abnormal retroperitoneal or paraspinous soft-tissue masses are seen. The size and position
of the conus medullaris appear normal.
L2-3: There is concentric annular disk bulge and accompanying marginal osteophyte. There is mild
ventral flattening of the thecal sac. There is mild to moderate degree of acquired spinal
stenosis. Facet arthropathy contributes to this.
L3-4: There is concentric annular disk bulge. There is mild ventral flattening of the thecal sac.
L4-5: There is intervertebral disk degeneration and concentric annular disk bulge. There is mild
ventral flattening of the thecal sac.
L5-S 1: There is intervertebral disk degeneration.
Impression: Mild to moderate central canal spinal stenosis at L2-3.
Interpretation of Medical Record
Abstract information from the medical record to complete the following questions.
1.Why was this patient referred to x-ray?
2. The L2-3 vertebral view showed the thecal sac flattened on what side of the spine?
3. Intervertebral disk degeneration was demonstrated at what levels?
4. At levels L3-5, the bulge is in a concentric annular shape. What does this mean?
5. Where is the conus medullaris located?
