78-year-old female with low back pain in the sagittal distribution. Multilevel spondylosis and disc bulges with anterolisthesis of L4 on L5. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Bone marrow signal is benign. The conus terminates at the distal L1 level.Individual levels as below:T12-L1: Mild disc bulge with no significant compromise to spinal canal or neural foramina.L1-2: Mild disc bulge with no significant compromise to spinal canal or neural foramina.L2-3: There is facet hypertrophy and ligamentum flavum hypertrophy. A disc bulge is present. These cause a mild spinal canal narrowing and mild left neural foraminal stenosis. L3-4: There is facet hypertrophy and ligamentum flavum hypertrophy. A disc bulge is present. These cause a moderate canal stenosis but no neural foraminal narrowing.L4-5: There is 8 mm of anterolisthesis and a disc bulge. There is facet hypertrophy and ligamentum flavum hypertrophy. A disc bulge is present. These cause a severe spinal canal stenosis with severe left and moderate right neural foraminal stenosis. L5-S1: A disc bulge is present without spinal canal stenosis. There is bilateral mild neural foraminal stenosis.Incidentally noted right renal cyst. A structure is seen to the right of descending aorta that is demonstrated on prior exams and is favored to represent a benign vascular or lymphoid structure.
1. Multilevel degenerative spondylosis and disc bulges. These result in spinal canal stenosis and neural foraminal stenoses that is worst at the L4-L5 level.2. Anterolisthesis measuring 8 mm of L4 on L5.
