Lung cancer and foot drop. There is no evidence of tumors within the lumbar spinal canal. There is mild multilevel lumbar spine degenerative spondylosis, without associated significant spinal canal or neural foraminal stenosis. There is prominent epidural lipomatosis at L5 and S1 through S3. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. There is a subcentimeter sclerotic focus in the left L5 pedicle, which likely represents an enostosis. There are scattered foci of fat in the vertebral bone marrow. There is no evidence of bone marrow metastases. The spinal cord and cauda equina nerve roots display normal signal and morphology. The paravertebral soft tissues are unremarkable. There is an incompletely imaged right renal cyst.
