title: [Cystic Rheumatoid Arthritis--case report].
abstract: Among the many radiological findings seen in Rheumatoid Arthritis RA small subchondral geodes and erosions are typical. Large geodes are far less common abnormalities and their presence may indicate diagnostic and therapeutic difficulties. We present a case report of a 55-year old woman with seronegative RA that developed a large geode in the knee with extensive joint destruction.
