Mar 15, 2025 · The primary risk factor is hyperuricemia, although only a small proportion of patients with hyperuricemia develop gout, often taking 20 to 30 years to develop. There are two mechanisms by which hyperuricemia can develop:

Feb 14, 2025 · Acute gouty arthritis, also known as a gout flare, is the acute symptomatic phase of gout due to the deposition of monosodium urate crystals in a synovial joint.

Mar 15, 2025 · Tophaceous gout is a form of chronic gout. Tophi typically involve the joint capsules and juxta-articular soft tissues such as tendons 7 or ligaments. The first metatarsophalangeal joint is the most commonly affected.

This patient subsequently had a joint aspiration which revealed negatively birefringent monosodium urate crystals confirming gout.

Classic x-ray findings of gout consists of juxta-articular and intra-articular erosions with sclerotic margins and overhanging edges. bone density is normal. Tophi can be seen as soft-tissue dense masses adjacent to the joints in chronic stages of the disease.

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.

A crystalline arthropathy such as gout or CPPD or in the appropriate clinical context, amyloid arthropathy are the favored diagnoses. Further evaluation with a duel energy CT of the wrist is suggested.

CONCLUSION: Appearances are consistent with progressive tophaceous gout causing bony destruction. Case Discussion Findings are typical of gout and this patient has a known history of gout.
