Lumbar pain, leg pain, evaluate for spinal stenosis or nerve entrapment. Ataxia. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits. There is mild diffuse heterogeneity of the bone marrow signal without discrete destructive osseous lesions. Small foci of T1 hyperintensity such as at L3 are compatible with foci of fat or small hemangiomas. The conus medullaris is normal in position.Mild degenerative changes are seen, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: Disc desiccation with small right annular fissure and right foraminal disc protrusion. There is mild narrowing of the right neural foramen with contact of the right L4 nerve root without clear evidence of impingement. No spinal canal or left neural foraminal narrowing. Mild bilateral facet arthropathy.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis. Mild bilateral facet arthropathy.Paraspinous soft tissues are within normal limits.
1. Mild degenerative changes in the lumbar spine including a small right foraminal disc protrusion at L4-L5 with mild right neural foraminal narrowing. Otherwise no significant spinal canal or neural foraminal stenosis in the lumbar spine.2. Mild facet arthropathy in the lower lumbar spine at L4-5 and L5-S1, which may be contributing to patient's low back pain. 3. Diffuse heterogeneity of the bone marrow signal which is nonspecific and can be seen with marrow reconversion related to chronic illnesses, anemia, and marrow proliferative disorders among various other etiologies. No discrete suspicious osseous lesion is demonstrated.
