Clinical question: Evaluate for? Progression of paraspinal muscle atrophy. Signs and symptoms: Pain, tenderness to palpation. Nonenhanced lumbar MRI:There is normal anatomical alignment the vertebral column.The signal intensity of vertebral column is unremarkable.Unremarkable no most visualized thoracic spine and thoracic cord.T12 -- L1 and L1 -- L2 levels are unremarkable.L2 -- L3 demonstrate mild disk desiccation. A tiny centrally located annular fissure is present. No spinal stenosis or neural foraminal compromise.L3 -- L4 demonstrate minimal disk desiccation and unremarkable otherwise.L4 -- L5 demonstrate mild disk desiccation and minimal bilateral ligamentum flavum hypertrophy. There is a linear increased T2/T2 stir signal within the annulus of the disk in the midline and consistent with an annular fissure. No spinal stenosis or neural foraminal compromise.L5 -- S1 demonstrate minimal degenerative changes and unremarkable otherwise.There is no detectable. Spinal soft tissue abnormalities and in particular no evidence of atrophy of paraspinal musculature are detected.
1.Tiny midline annular fissure at L2 -- L3 and a slightly larger midline annular fissure at L4 -- L5 levels are noted.2.Unremarkable exam otherwise and without spinal canal or neuroforaminal compromise at any level.3.No detectable paraspinal soft tissue abnormalities.
