 The last well formed disk space is referred to as L5-S1. There are postoperative findings related to L3, L4 and L5 laminectomies with mild regional postoperative soft tissue enhancement. There is a hemangioma in T12 vertebral body. Vertebral body alignment is normal. Vertebral body heights are intact. There is desiccation of multiple lumbar disks. The conus terminates at L1-2.T12-L1: No disk herniation or spinal stenosis.L1-2: No disk herniation or spinal stenosis.L2-3: Mild disk bulge and facet arthropathy with the ligamentum flavum thickening. No significant spinal canal or neural foraminal stenosis.L3-4: Mild disk bulge with small central disk protrusion, facet arthropathy, and laminectomy. No significant spinal canal or neural foraminal stenosis.L4-5: Diffuse disk bulge with small right paracentral and far lateral disk protrusion with annular fissure, facet arthropathy, and laminectomy. No significant spinal canal stenosis. Minimal bilateral neural foraminal stenosis.L5-S1: Diffuse disk bulge, advanced facet arthropathy with ligamentum flavum thickening, and laminectomy. No significant spinal canal or neural foraminal stenosis.Dedicated images through the sacrum show no discernible mass, nerve root thickening or suspicious enhancement in the sacral foramina. There is minimal increased STIR signal seen in the inferior and lateral margins of the sacrum bilaterally, somewhat symmetric in appearance. This may reflect artifact versus minimal edema. However, there is no osseous erosion or fluid collection.There is a right renal exophytic cystic lesion incompletely imaged, probably representing a simple cyst.
1.No mass or nerve root thickening in the sacral foramina, as questioned on the prior radiograph.2.Questionable increased STIR signal in the far inferior and lateral margins of the sacrum bilaterally. This may reflect artifact versus minimal edema.3.Postsurgical findings and mild multilevel lumbar spondylosis as described above.
