Sonographic Recognition of Gout: Core Imaging Pearls

This lecture reviews the ultrasound features of gout, including the double contour sign and tophi, in a condition that typically presents as acute monoarthritis of the first MTP joint in men >40 with hyperuricemia.

• Gout is a crystal arthropathy from monosodium urate deposition, primarily affecting the first metatarsophalangeal joint (podagra) in middle-aged males with metabolic risk factors.
• Key ultrasound findings include the hyperechoic double contour sign over articular cartilage and intra- or periarticular tophi with surrounding hypoechoic halos.
• Educational video from Radquarters; no formal study design or validation data are provided.
