Gout : Radiographic Features

slide 10 of 28

55 y/o male with painful swelling of foot. There are several well-circumscribed punched-out bony erosions with sclerotic margins, especially at first metatarsophalangeal joints, bilaterally. Juxta-articular soft tissue densities and swelling are also visible. Findings of x-rays are characteristic of tophaceous gout.

The typical appearance of gout on x-ray evaluation is the presence of well-defined “punched-out” erosions with sclerotic margins in a marginal and juxta-articular distribution, with overhanging edges. Tophi are pathognomonic feature of gout.
