Clinical question: Rule out cord compression. Signs and symptoms: Numbness. Nonenhanced total spine MRI:Examination demonstrates normal signal intensity and anatomic alignment the vertebral column other than mild grade 1 anterolisthesis at L5 -- S1 which is believed to be secondary to degenerative disease.Examination in the cervical region demonstrate degenerative changes with resultant mild central spinal stenosis at C6 -- C7. The signal intensity and caliber cervical cord remains within normal.Examination of thoracic spine demonstrate normal signal intensity and caliber of cord without evidence of mass effect. No appreciable degenerative changes, spinal canal or neural foraminal compromise is present.MRI images of lumbar region demonstrate a centrally located disk protrusion with partial effacement of ventral subarachnoid space and no significant central spinal stenosis. The signal intensity of conus and the cauda equina demonstrate no abnormality. No evidence of spinal canal compromise at any other level.Mild grade 1 anterolisthesis at L5 -- S1 secondary to pars defect. This finding can be further assessed with a dedicated MRI of the lumbar spine.
1.No evidence of cord compression.2.Degenerative changes at C6 -- C7 results in mild central spinal stenosis. 3.Small disk protrusion at L1 -- L2 with partial effacement of ventral subarachnoid space as detailed.4.Grade 1 anterolisthesis at L5 -- S1 secondary to pars defect. Dedicated MRI of lumbar spine is recommended for further assessment. There is no evidence of spinal stenosis with this finding.
