慢性痛风导致尿酸盐沉积为似白垩的物质，即痛风石。这种痛风石会破坏关节及相邻的骨，图示的两张X线片均为病人右足(只不过做了两次X线拍摄)，大多数但非所有情况会有高尿酸血症。

Chronic gout leads to deposion of urates into a chalky mass known as a "tophus". Such tophi can destroy the joint and adjacent bone as seen here radiographically in sequential radiographs of the same foot (the patient did not have two right feet). In most, but not all, cases there is hyperuricemia.
