 The lower lumbar spine is congenitally narrowed on the basis of pedicle hypoplasia. There is minimal retrolisthesis of L4 on L5. There is no focal high-grade stenosis. There are no fractures or subluxations. There is a nonspecific focus of T1 hyperintensity in the T11 vertebral body. The conus is normal in signal and morphology and terminates at the L2 level. The visualized intra-abdominal and paraspinal contents are unremarkable.T12/L1: No significant spinal canal or neuroforaminal narrowing.L1/2: No significant spinal canal or neuroforaminal narrowing.L2/3: No significant spinal canal or neuroforaminal narrowing.L3/4: Mild diffuse disc bulge with minimal spinal canal narrowing and mild bilateral neuroforaminal narrowing.L4/5: There is a left paracentric disc protrusion with effacement of the left lateral recess, which may be impinging the traversing left L5 nerve root. No significant focal high-grade stenosis in the spinal canal or neuroforamina.L5/S1:There is a central disc protrusion without significant spinal canal or neuroforaminal narrowing.SI joints: There is a presumed bone island adjacent to the right SI joint in the right ileum.
1.Minimal retrolisthesis of L4 on L5 with a left paracentric disc protrusion with effacement of the left lateral recess, which may be impinging on the traversing left L5 nerve root. 2.Congenitally narrowed lower lumbar spine on the basis of pedicle hypoplasia. Otherwise no significant central canal stenosis is appreciated in the lumbar spine.3.Focus of T1 hypointensity and T2 hyperintensity in the T11 vertebral body may represent an atypical hemangioma but is nonspecific.
