Female, 17 years old, with pain/pressure in the left buttock, status post discectomy May 2015. Spinal alignment is within normal limits. Vertebral body heights are maintained. Bone marrow signal intensity is within normal limits. The visualized spinal cord, conus and cauda equina demonstrate normal signal intensity and morphology. L1-2: Mild facet hypertrophy. No significant spinal canal or neuroforaminal stenosis. L2-3: Mild facet hypertrophy. No significant spinal canal or neuroforaminal stenosis. L3-4: Moderate facet hypertrophy. Mild disc bulging with a small right paracentral protrusion. No significant generalized spinal canal stenosis. No significant neuroforaminal narrowing. L4-5: Evidence of laminotomy on the left. Severe facet hypertrophy. Small defect in the left paracentral disc may reflect a prior treated herniation. There may be a tiny right paracentral protrusion with mild disc bulging and loss of disc T2 signal. No significant generalized spinal canal stenosis. Mild foraminal narrowing. L5-S1: Facet hypertrophy, severe on the left. Mild bulging disc. No significant generalized spinal canal stenosis. No significant neuroforaminal narrowing.
1.Evidence of laminotomy on the left at L4-5 compatible with the surgical history.2.Disc degeneration at L4-5 but without significant spinal canal stenosis or foraminal compromise.3.Relative mild disc disease at other levels. However, advanced facet arthropathy is seen at L4-5 and L5-S1.
