Diagnosis: Acquired spondylolisthesis LumbagoClinical question: L5-S1 spondylolisthesis, look for cord involvementSigns and Symptoms: Back pain, RLE radiculopathy Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The conus medullaris on sagittal imaging is grossly intact. There is multilevel disc desiccation present.At L5-S1 there is no significant compromise to spinal canal or neural foramina. There is marked bilateral facet hypertrophy present at this level. There is partial effacement of the fat at the lateral recesses sees at this level and some mild narrowing of the neural foramina.At L4-5 there is a cystic type lesion adjacent to the right facet joint which mildly displaces the thecal sac and effaces the fat surrounding the nerve roots at the right lateral recess. There is a moderate degree of bilateral facet hypertrophy at this level. The fat surrounding the nerve roots within the neural foramina is not effaced.At L3-4 there is no significant compromise to spinal canal or neural foramina.At L2-3 there is no significant compromise to spinal canal or neural foramina.At L1-2 there is no significant compromise to spinal canal or neural foramina.
1.There is a synovial cyst present at the right lateral recess at L4-5 which encroaches on the nerve roots at the right lateral recess.2.There are marked facet degenerative changes present at L5-S1. Please note that this examination was obtained with the patient in the supine position. The subluxation noted on the plain films is not readily appreciated on the current exam.
