2024年10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.

2024年7月9日 · Ultrasound. While there can be variation in appearance, tophi tend to be hyperechoic, heterogeneous, and have poorly defined contours. They can form multiple groups with surrounding anechoic haloes 8. Additional findings may include: echogenic, irregular bands apposed to articular cartilage 15,16. synovial thickening. with increased vascular flow
Advanced Imaging in Gout - AJR
2013年8月23日 · Dual-energy CT can quantitatively identify monosodium urate crystal deposits with high sensitivity and specificity within joints, tendons, and periarticular soft tissues. There are several characteristic ultrasound imaging findings, which include visualization of echogenic monosodium urate crystal deposition, tophus, and adjacent erosions.
(a) Longitudinal ultrasound image of the medial surface of the elbow (p, proximal; d, distal) showing tophus outside the olecranon bursa. Tophus is hyperechoic, heterogeneous (t, dotted line between Xs) with imprecise posterior contour, leading to bone erosions (white arrowheads).
Images in Primary Care Medicine: Point-of-Care Ultrasound in Gout
Gout is the most common crystal arthropathy and is frequently diagnosed and managed by primary care physicians. Point-of-care ultrasound (POCUS) is a valuable tool to aid in the diagnosis of gout via the identification of the double contour sign, …
Ultrasound features of tophi in chronic tophaceous gout
2010年7月31日 · Ultrasound images of 138 affected areas were analyzed from 31 patients with gout, using high-quality broadband linear transducers (frequency range of 8–14 MHz). Tophi were classified relative to echogenicity, echotexture, contours, number and the presence or absence of hypoechoic halo.

2009年6月17日 · Ultrasonography patterns indicating the presence of gout. (a) Double contour sign: transversal ultrasound imaging of the knee joint in the anterior intercondile area. The double contour image is shown as an anechoic line paralleling bony contour femoral cartilage.
Imaging of gout: findings and pitfalls. A pictorial review
2021年1月20日 · The most sensitive and specific imaging methods for diagnosing acute gout are ultrasound and dual energy computed tomography (DECT). In the chronic or tophaceous gout, imaging may depict tophi and their local destructive effect on surrounding tissues with characteristic findings on radiographs.
