Long history of ankylosing spondylitis. The vertebral bodies are preserved in height. There is no squaring of the vertebrae. The intervertebral discs are preserved in height and T2 signal, other than mild loss at L4-L5 along with slight disc bulging. There is no significant spinal or neural foramen stenosis. The spinal cord and conus medullaris show normal morphology and signal. The facet joints show no excessive fluid or gross erosive change. Only the upper portions of the sacroiliac joints is included and shows no edema, sclerosis, or fusion.
1. No specific findings to support the diagnosis of ankylosing spondylitis. However, this diagnosis can be subtle on MRI and is better assessed by radiographs.2. Mild L4-L5 degenerative disc disease but no significant spinal canal or neural foramen stenosis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
