Male, 45 years old, with low back pain. Spinal alignment is anatomic the vertebral in morphology and signal characteristics are within normal limits. No evidence of marrow edema is detected. The spinal cord, conus and cauda equina are within normal limits.L1-2: Unremarkable. No significant interval changes. L2-3: Mild facet hypertrophy. No significant spinal canal or neuroforaminal stenosis. No significant interval changes. L3-4: Mild facet hypertrophy. Mild laterally bulging disk. No significant spinal canal or neuroforaminal stenosis. No significant interval changes. L4-5: Moderate facet hypertrophy. Loss of disk T2 signal. Laterally bulging disk with a left paracentral annular fissure. On the prior examination, there was a small protrusion at the level of the annular fissure which seems to have resolved. No significant spinal canal stenosis. Mild bilateral foraminal narrowing L5-S1: Moderate facet hypertrophy. Mild bulging disk with a small central annular fissure which was questionably present on the prior examination. No significant spinal canal stenosis. Mild bilateral foraminal narrowing. No significant interval changes.
1. Mild degeneration of the intervertebral disks without evidence of any high-grade spinal canal or neuroforaminal stenosis. 2. A small left paracentral disk protrusion seen on the prior examination at L4-5 seems to have resolved. 3. No additional findings are seen which would account for the patient's low back pain.
