Other intervertebral disc degeneration, lumbosacral region [M51.37], Reason for Study: ^Reason: assess for lumbar pathology History: low back pain with radiculopathy. Prostate cancer history. For the purpose of this dictation, the lowest visualized intervertebral disc space is labeled L5-S1. Diffuse low signal intensities on lumbar spine indicate replacement of normal fatty marrow.Normal fatty marrow signal intensity on sacrum and bilateral ilium were seen which is consistent with prior radiation therapy related changes.The spine alignment is anatomic. The vertebral body height is preserved. The signal of the visualized cord is normal. The conus medullaris terminates at the L1 level.The intervertebral discs demonstrate normal T2 intensity and height with no evidence of disc herniation. The paraspinal soft tissues are unremarkable.There is no evidence of abnormal enhancement, cord compression or mass. Degenerative changes are specified by the intervertebral level as follows: T12-L1: no neuroforaminal narrowing or spinal stenosis. L1-L2: no neuroforaminal narrowing or spinal stenosis. L2-L3: no neuroforaminal narrowing or spinal stenosis. L3-L4: Schmorl's node on both superior and inferior end plates. Diffuse bulging of disc with bilateral ligamentum flavum thickening results mild spinal canal stenosis. Mild left side neuroforaminal stenosis is seen. L4-L5: diffuse bulging of disc with bilateral ligamentum flavum thickening results mild spinal canal stenosis. Mild bilateral neuroforaminal stenosis are seen.L5-S1: no neuroforaminal narrowing or spinal stenosis.
1. Diffuse replacement of normal fatty marrow of lumbar vertebral bodies, this may indicate possible diffuse metastasis or conversion to red marrow.2. Multilevel various degree degenerative change of lumbar spine, in particular, L34 and L45 level shows mild spinal canal stenosis.
