 Alignment is anatomic. No loss of vertebral body height. The marrow signal is benign. The conus is normal in signal and morphology and terminates at an appropriate level. The visualized intra-abdominal and paraspinal contents are unremarkable. L1/2: No evidence foraminal narrowing or spinal canal stenosis. L2/3: Mild hypertrophy of the ligamentum flavum and disk dessication. No evidence of neuroforamina or central canal stenosis.L3/4: Mild hypertrophy of the ligamentum flavum and disk dessication. No evidence of neuroforamina or central canal stenosis.L4/5: Mild hypertrophy of the ligamentum flavum and disk dessication. No evidence of neuroforamina or central canal stenosis. L5/S1: Ligamentum flavum hypertrophy, right greater than left. Mild disk desiccation and loss of disk height. Moderate right neural foraminal narrowing. No evidence of left neural foraminal narrowing or central canal stenosis. Sacrum: Expansion of the thecal sac with bony remodeling of the neuroforamina bilaterally, right greater than left. There is extension to the S2 neuroforamina with mild mass effect with forward displacement and flattening of the right S2 nerve root. There is lesser mass effect on the left S2 nerve root. There is no abnormal signal of the nerve roots.
1.Expansion of the thecal sac with bony remodeling of the sacral neuroforamina bilaterally, right greater left. There is mild mass effect on the S2 nerve roots bilaterally, right greater than left. The differentials include prominent Tarlov cysts, perineural cyst, or arachnoid cyst. Myelogram with delayed imaging will be helpful for further evaluation.2.Degenerative disk disease as above, without significant central canal stenosis.
