Disorder of brain, unspecified [G93.9], Reason for Study: ^Reason: increasing weakness RLE History: increasing weakness RLE There is normal thoracic kyphosis and lumbar lordosis. The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. The conus medullaris terminates at the T12 level.The paraspinal soft tissues are unremarkable.There is no evidence of abnormal enhancement, cord compression or mass. Incidental finding of the left renal cyst (about 20mm in diameter).Degenerative changes are specified by the intervertebral level as follows: T11-T12: There is broad based disc protrusion toward right side neural foramen which results moderate to severe neural foraminal stenosis.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: Mild disc desiccation. Diffuse bulging of disc with bilateral ligamentum flavum thickening causing minimal spinal canal stenosis. Broad-based disc bulging toward left side neural foramen causing minimal neural foraminal stenosis on the left side. L4-L5: Disc desiccation. Diffuse bulging of disc with bilateral ligamentum flavum thickening causing mild to moderate spinal stenosis. L5-S1: Disc desiccation. Diffuse bulging of disc causing minimal spinal canal stenosis.
1. Spinal cord signal intensity is normal.2. Degenerative changes of lumbar discs. In particular, there is a broad-based disc protrusion toward the right side neural foramen at the level of T11-12.3. Degenerative various degree spinal canal stenosis at the level of L34, L45 and L5S1.
