X ray Findings of chronic gouty arthritis

What are the radiographic features of chronic gouty arthritis

• Erosions with sclerotic margins and an overhanging edge. These are caused by tophaceous deposits in the synovium slowly expanding into bone. The bone reacts and forms a sclerotic margin around the erosion.

  • • Relative preservation of joint space until late in disease.
  • • Relative lack of periarticular osteopenia for the degree of erosion seen.
  • • Nodules in soft tissue (i.e., tophi) near involved joints. Unlike rheumatoid nodules, tophi can become calcified.
