Low back pain. Five lumbar vertebrae are identified with a lumbosacral transitional morphology of L5. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. There is mild disc desiccation at L3-4. There is mild, diffusely decreased T1 signal within the bone marrow which remains hyperintense to skeletal muscle and which may be related to red marrow. Additional scattered foci of increased T1 and T2 signal within the vertebral bodies are compatible with benign hemangiomas and/or focal fat deposition. There is an area of cortical irregularity and/or defect involving the anterior inferior lateral aspect of the left T12 vertebral body with associated edema signal within the vertebral body. In addition, there is asymmetric enlargement and edema involving the left psoas muscle from T12 to approximately L4 without associated discrete collections.Mild facet arthropathy affects the lower lumbar spine. No significant disc pathology is noted within the lumbar spine. No significant central canal or foraminal stenosis. The visualized spinal cord, conus and nerve roots of the cauda equina are within normal limits.
1.Left anterolateral cortical irregularity and associated bone marrow edema involving the T12 vertebral body which is nonspecific but may reflect traumatic injury. There is associated edema involving the left psoas muscle. CT of the thoracolumbar lumbar spine is recommended for additional evaluation.2.Minimal degenerative changes of the lumbar spine without significant central canal or foraminal stenosis.
