Abstract

Background: Ultrasound is increasingly used in gout diagnosis and it is inexpensive, noninvasive, and very sensitive for detecting urate crystal deposition. However, the factors associated with the appearance of signs on ultrasound are still unknown. Objective: To investigate some imaging characteristics of ultrasonography and related factors in patients with gouty arthritis. Materials and methods: A cross-sectional descriptive study of 39 patients admitted to the Department of General Internal Medicine, Can Tho University of Medicine and Pharmacy Hospital from June 2020 to December 2022. Results: Double contour sign was the most common sign on ultrasound (66.7%), followed by knee effusion (46.2%), synovial hypertrophy (38.5%) and nodules tophi (23.1%). The number of inflammatory joints and duration of disease were associated with double line markers (p = 0.008 and p = 0.025), like disease duration with tophi (p = 0.028), while knee effusion correlated with the number of white blood cells in the blood (p = 0.007). Conclusion: Double contour sign, tophi, knee effusion, synovial hypertrophy are signs that can significantly help diagnose gout through joint ultrasound.
