GOUT-RADIOGRAPHY

SUMMARY

1. Tophi: typically located in the peri-articular area along the extensor surface, but maybe intra-articular or not associated with the joint at all.


2. Punched out erosions: borders can be sclerotic because of the indolence of the process, creating a punched-out or "rat bitten" appearance.


3. Sclerotic, overhanging edges: as the erosion develops, the edges of the cortex can be remodelled in an outward fashion, creating an overhanging edge.


4. Intraosseous lesions: intraosseous tophi.


5. There is preserved joint space and no periarticular osteopenia.
