Female, 54 years old, with dermatomal distribution of neuropathic pain. History of diabetes and polyneuropathy. Spinal alignment is within normal limits. Vertebral body heights are maintained. Bone marrow signal intensity is within normal limits. The visualized spinal cord, conus and cauda equina demonstrate normal signal intensity and morphology. The intervertebral disk spaces are preserved. Loss of disc T2 signal is seen at L3-4 and L4-5. Additional level specific findings are as follows:L1-2: Unremarkable. L2-3: Unremarkable. L3-4: Right greater than left facet hypertrophy. Left foraminal disc protrusion resulting in moderate narrowing of the left neural foramen and probable mild impingement of the exiting left L3 nerve root. No significant generalized spinal canal stenosis. L4-5: Facet hypertrophy. Ligamentum flavum thickening. No significant spinal canal stenosis. Mild left foraminal narrowing. L5-S1: Right greater than left facet hypertrophy. No significant spinal canal or neuroforaminal stenosis.
1.A left foraminal zone disc protrusion at L3-4 results in moderate foraminal narrowing and probable mild impingement of the exiting L3 nerve root.2.Minimal degenerative findings are seen at other levels without significant spinal canal or neuroforaminal stenosis.
