CT ANKYLOSING SPONDYLITIS POSTERIOR SPINAL FUSION 1
WHAT ARE THE FINDINGS?
- This is a T1 weighted scan.
- There is bilateral facet joint fusion and ankylosis (no joint space seen) in a patient with ankylosing spondylitis.
- The high (white) signal seen in the facets is a chronic reactive change of fatty change post inflammation.
