Male, 18 years old, left lower leg pain since 8/2014, positive left straight- leg exam, concern for radiculopathy. Spinal alignment is anatomic. Vertebral body morphology is within normal limits. No evidence of marrow replacement or marrow edema is seen.The visualized spinal cord, conus and cauda equina are unremarkable.The L5-S1 disk demonstrates loss of T2 signal. There is, in addition, a left paracentral disk protrusion which narrows the left ventral thecal sac and probably impinges upon the transiting left S1 nerve root.Mild facet hypertrophy is seen at L5-S1 which, along with the disk herniation, contributes to a mild left neuroforaminal narrowing. No significant degenerative disease is seen at the remaining levels and there are no other areas of spinal canal or foraminal stenosis.
Left paracentral L5-S1 disk herniation with probable impingement of the left S1 nerve root.
