The analysis of morphological features and ultrasonographic characteristics of Dupuytren’s disease

Objectives: To detect B-Mode ultrasonography, color Doppler ultrasonography, and sonoelastography findings of the Dupuytren’s disease, and to determine the differences of sonographic imaging, demographic and clinical data. Methods: A total of 88 patients with unilateral lesion were included. Each lesion was evaluated with B-Mode ultrasonography, color Doppler ultrasonography, and sonoelastography. The location, size, morphology, and echogenicity of the lesions were analyzed by B-mode ultrasonography, the presence of vascularization by color Doppler ultrasonography, and the elasticity by sonoelastography, retrospectively. The differences between sonographic findings, demographic and clinical data were evaluated. Results: Of the patients, 36.4% were women and 63.6% were men, with a median age of 61 (interquartile range: 9). The majority of the lesions (87.5%) were at the level of the 3rd and 4th finger/metacarpal. Median longitudinal dimension was 6.75mm (interquartile range: 4.32), mediolateral dimension was 2.5 mm (interquartile range: 1.77). Of the lesions, 67.1% were nodular shaped, 73.9% were hypoechoic, and 87.5% were hypovascular. All lesions were hard coded on sonoelastography. The cord morphology, extension to the tendon, and contracture tend to be together, and lesions with these were mostly iso-hyperechoic. Conclusion: Dupuytren’s disease lesions were mostly nodular, hypoechoic, hypovascular, and stiff. Ultrasonographic examination was sufficient and successful in the diagnosis of Dupuytren’s disease.
