"Acute gout most commonly presents as a monoarthritis of the lower limb, classically involving the first metatarsophalangeal joint (podagra). Other commonly affected sites include the ankle and knee, with the wrist and interphalangeal joints also potentially involved. Less commonly, the hip, shoulder, and vertebral column joints may be involved. Polyarticular joint involvement is seen in long-term, untreated gout and as an atypical presentation in post-menopausal women."

"Ultrasound scans have a diagnostic role in assessing gouty joints. Joint inflammation, synovitis, hypertrophy and bony erosions can be seen on ultrasound scans. Features specific to gout include double contour cartilage line, visualising urate crystal deposition and tophaceous material."
