Male, 20 years old, with back pain. Assess for stenosis. The lumbar lordosis is straightened but spinal alignment is otherwise unremarkable. Vertebral body height and morphology are normal. No concerning marrow replacement or marrow edema is seen. The visualized distal spinal cord, conus and cauda equina are unremarkable except as discussed below.L1-2: Unremarkable. L2-3: Unremarkable. L3-4: Very mild loss of disc height and disc T2 signal. Small central disc protrusion which mildly effaces the ventral thecal sac. No significant generalized spinal canal stenosis or specific nerve root impingement is suspected. The neural foramina are patent. No interval changes are seen. L4-5: Mild facet hypertrophy is otherwise unremarkable. No significant interval changes. L5-S1: Loss of disc height and T2 signal. Moderately sized right paracentral disc protrusion which effaces the right lateral recess and which contacts and displaces the transiting right S1 nerve root. The right neural foramen is only mildly narrowed and the exiting right L5 nerve root does not appear to be impinged. The left neural foramen is patent. These findings are unchanged.
1.No significant change in the size or morphology of a right paracentral disc protrusion at L5-S1 which effaces the right lateral recess and potentially impinges the transiting right S1 nerve root.2.No significant change in the size or morphology of a small central disc protrusion at L3-4 which causes no significant generalized spinal canal stenosis or nerve root impingement.3.No new or acute findings are identified.
