Spinal stenosis, lumbar region [M48.06], Reason for Study: ^Reason: back pain History: back pain For the purpose of this dictation, the lowest visualized intervertebral disc space is labeled L5-S1. Spinal cord diminished at the level of L3-4 level, unchanged since prior scan. L5 vertebrae showed spina bifida, unchanged.Vertebral heights are preserved.Vertebral body signal intensity appears to be normal.There is normal lumbar lordosis. The spine alignment is anatomic. The signal of the visualized cord is normal. The right side renal cysts are again seen, grossly unchanged.Degenerative changes are specified by the intervertebral level as follows: T12-L1: no neuroforaminal narrowing or spinal stenosis. L1-L2: No evidence of spinal canal stenosis. No neuroforamen stenosis.L2-L3: Minimal bulging of disc, more prominent toward left side with left side mild to moderate neuroforaminal narrowing.L3-L4: Diffuse bulging of disc with bilateral ligamentum flavum thickening results moderate to severe spinal canal stenosis as well as bilateral lateral recess narrowing. Slightly advanced since prior scan.. L4-L5: Diffuse bulging of disc with bilateral ligamentum flavum thickening results moderate to severe spinal canal stenosis as well as bilateral lateral recess narrowing. Slightly advanced since prior scan. Unchanged since prior scan. L5-S1: Minimal bulging of disc with prominent right side facet joint, unchanged since prior scan.
1. Lower lying conus at the level of L34 without evidence of spinal cord signal abnormality, unchanged.2. Slightly progressed L34 spinal canal stenosis since prior scan.3. Multilevel degenerative changes of lumbar spine, grossly unchanged since prior scn.
