Arthritides

1. Osteoarthritis – may be multiple ‘cysts’ in the load-bearing areas of multiple joints. Surrounding sclerotic margin. Joint-space narrowing, subchondral sclerosis and osteophytes.

2. Rheumatoid arthritis* – no sclerotic margin. Begins periarticularly near the insertion of the joint capsule. Joint-space narrowing and juxta-articular osteoporosis.

3. Calcium pyrophosphate arthropathy (see Calcium pyrophosphate dihydrate deposition disease*) – similar to osteoarthritis but frequently larger and with more collapse and fragmentation of the articular surface.

4. Gout – ± erosions with overhanging edges and adjacent soft-tissue masses.

5. Haemophilia*.

Neoplastic

1. Metastases/multiple myeloma*.

2. Aneurysmal bone cyst* – solitary.

3. Giant cell tumour* – solitary.

4. Chondroblastoma* – solitary.
