In patients with gout, during acute arthritis attacks, a non-characteristic shadow of soft tissue swelling can be seen on a typical x-ray. Alternatively, in the chronic phase or after repeated attacks, destruction of the cartilage rim and irregularity of the joint surface can be seen. The characteristic changes are the appearance of chisel-like or worm-like round, or arc-shaped translucent defects of bone, a condition of bone erosion. Gout is a metabolic rheumatic disease, the underlying cause of which is a disorder of purine metabolism that leads to high concentrations of uric acid in the blood, resulting in a group of diseases. Long-term elevated uric acid deposits in the joints and surrounding tissues, and chronic attacks eventually lead to erosion-like changes in the joints. In addition, gout stones can develop and be deposited in tissues and organs, leading to dysfunction.
