A 65-year-old man was referred by his orthopedic surgeon to the outpatient radiology section of a local hospital for myelography and spine CT because of lower back pain and clinical findings suggesting spinal stenosis. A hospital-based interventional radiologist performed the lumbar puncture, administered contrast medium intrathecally, obtained my-elographic images, and supervised the CT examination. The entire procedure was uneventful. The patient was later discharged and was driven home by a relative. The radiologist interpreted the study as disclosing spinal stenosis without evidence of other pathology.
