54F medial knee pain and mass. Lump for years. Difficulty walking.

2 Comments / Cases / By

Pre and post gad. Patient afebrile. Palpable lump. No skin discoloration.
The bright thing at the skin is an oil pill used as a marker for
localization purposes. Oh she also has a meniscus tear.

What is the mass?

1. Abscess.
2. Chondrosarcoma.
3. Adventitial bursitis as a result of chronic friction associated with a
preexisting osteochondroma.
4. Silicone injection for knee “enhancement”.
5. Lyme’s disease.

Please reply to me. I’ll summarize.

    Looks like adventitial bursitis secondary to osteochondroma (growing away from the joint).

    Nice case
