2025年1月8日 · Gout is a crystal arthropathy due to deposition of monosodium urate crystals in and around the joints. Typically occurs in those above 40 years. There is a strong male predilection of 20:1, with this predilection more pronounced in younger and middle-aged adults. In the elderly, the gender distribution is more equal 13.

X-Ray Interpretation. Gout is caused by the deposition of monosodium urate crystals. About 50% of patients manifest radiographic bony changes, usually 6-8 years after the initial attack. These changes depend on the sites where the urate crystals are deposited. The following are features of chronic tophaceous gout.

The imaging findings of gout in hand radiography include an asymmetrical polyarticular distribution, juxta-articluar eccentric and lobulated soft tissue masses due to tophus deposition, normal mineralization, well-defined erosions with sclerotic margins ( punched-out lesions) and overhanging margins . There is preference of joint involvement in ...

Gout. There are large tophaceous deposits (white arrows) surrounding several of the joints of the right hand. There are juxta-articular, punched-out lytic erosions (white and yellow circles) and a lack of osteoporosis characteristic of gout. The erosions are shown in close-up view (blue arrows).

Conventional radiography of both hands showing multiple punched out erosions (arrowheads) and soft tissue densities (tophi; arrows) typical of gout. In the trial setting, CR has been utilized as an outcome tool.

PA radiograph of the right hand shows erosive and cyst-like changes about multiple joints of the hand and ulnar styloid with adjacent dense soft-tissue nodules (arrows) consistent with gouty arthropathy. Several erosions have overhanging edges, most notable at the radial aspect of the index finger proximal interphalangeal joint.

4 天之前 · The great toe demonstrates extensive juxta-articular erosions. Gout. There are characteristic erosions with "overhanging" edges seen in gout (white arrows). These have been characterized as appearing like "rat-bites."

2009年6月17日 · Imaging is a helpful tool for clinicians to evaluate diseases that induce chronic joint inflammation. Chronic gout is associated with changes in joint structures that may be evaluated with diverse imaging techniques. Plain radiographs show typical changes only in advanced chronic gout.

Gout is the most common of the crystal arthropathies. Unlike rheumatoid, gout does not usually have a symmetric distribution. It most commonly affects the first metatarsophalangeal joint. In patients with acute gout the X-ray may appear normal. Juxta-articular erosions become visible in …
