Sagittal magnetic resonance images of ankle region: psoriatic arthritis. (a) Short tau inversion recovery (STIR) image, showing high signal intensity at the Achilles tendon insertion (enthesitis, thick arrow) and in the synovium of the ankle joint (synovitis, long thin arrow). Bone marrow oedema is seen at the tendon insertion (short thin arrow ...
Synovitis causes joint tenderness or pain, swelling and hard lumps, called nodules. When associated with rheumatoid arthritis, swelling is a better indicator than tenderness. The joints in your hands and fingers feel painful when pressed and when moving or gripping anything.

PVNS (Pigmented villonodular synovitis): is a joint problem that usually affects the shoulder, hip or knee. It can also affect the elbow, ankle, and hand or foot. In pigmented villonodular synovitis, the synovial joint lining becomes swollen and grows. It may harm the bone around the joint.
[10] [11] [12] Other underlying disorders include vasculitides such as polyarteritis nodosa. [8] Other causes of edema include heart failure, hypoalbuminemia, nephrotic syndrome and venous stasis. The key distinguishing feature is that these conditions don't tend to manifest with pitting edema at the back of the hands.
Villonodular synovitis is a type of synovial swelling. Types include: Pigmented villonodular synovitis; Giant cell tumor of the tendon sheath; Though they have very different names, they have the same histology, and stain positive for CD68, HAM56, and vimentin. [1] They are sometimes discussed together. [2] [3] [4]
