CASE
A 17-year-old male presented to his family physician with low back pain that had progressively worsened over the past few months. At presentation, he was starting to have weakness in both of his legs as well. The physical examination revealed mild soft tissue swelling along the upper lumbar spine and a mild decrease in strength and reflexes in the patient's lower extremities. The physician ordered radiographs of the lumbar spine (Figure 1). What does the radiograph show?
