Answer: Synovial chondromatosis
What to look for in synovial chondromatosis
- Multiple small, similar-sized calcified or ossified loose bodies within a joint.
- Knee and hip are the commonest sites.
- Joint space is often preserved early, which helps distinguish it from osteoarthritis with loose bodies.
Description by the image author (may be in another language): Synovial chondromatosis (a collection of loose cartilagenous bodies which may or may not calcified) occuring within Baker's cyst (fluid-filled lesion lined by synovium, located within the popliteal fossa, that communicates with the knee joint).
Educational case. The diagnosis comes from the image's documented source; the "what to look for" list describes the condition in general and is not a report of this individual image.
