Erosions with overhanging edges are generally considered pathognomonic for gout (though also found in other diseases). Characteristics of erosions typical of gout include the following:

  • Maintenance of the joint space

  • Absence of periarticular osteopenia

  • Location outside the joint capsule

  • Sclerotic (cookie-cutter, punched-out) borders

  • Asymmetric distribution among the joints, with a strong predilection for distal joints, especially in the lower extremities
