Sonographic monitoring of gout

Abstract

Objective: To assess the role of grayscale and power Doppler sonography in short-term monitoring of acute gouty synovitis. Methods: Clinical and sonographic assessments were performed in a patient with gout. Clinical and sonographic evaluations were performed within the first day of the acute onset of synovitis of the first metatarsophalangeal joint of the left foot and 7 and 14 days after the baseline assessments. The patient was treated only with colchicine. Results: At baseline, both grayscale and power Doppler sonography revealed clearly evident findings of acute synovitis (joint cavity widening, thickening of periarticular soft tissues and power Doppler signal). After seven days, a complete clinical remission occurred. Ultrasound examination revealed marked improvement with respect to the basic findings, even if all the sonographic features of joint inflammation were still detectable. Two weeks after the onset of the acute attack, clinical remission was maintained and all the sonographic features of synovitis disappeared. Conclusion: Sonography is a sensitive and reliable tool for assessing and short-term monitoring of acute gouty attack.
