Objective:To explore the two-dimensional ultrasonography features of localized gallbladder adenomyomatosis.Methods:Thirty patients with pathologically proved localized gallbladder adenomyomatosis were enrolled in this study,and the two-dimensional ultrasound imaging characteristics were analyzed retrospectively.Results:Twenty-eight(93.1%)lesions located at the bottom of the gallbladder,29(96.7%)lesions were broader base,28(93.1%)lesions were hypoechoic or iso-echoic,29(96.7%)cases were with integrated gallbladder wall,cystic regions were detected in 21(70.0%)lesions,tiny bright-echo were shown in 12(40.0%)lesions.Color Doppler Flow imaging did not detect blood signal in 28(93.1%)lesions.Diagnostic accuracy of localized gallbladder adenomyomatosis were 70% when combined with high-frequency ultrasound.Conclusions: The two-dimensional ultrasound imaging of localized gallbladder adenomyomatosis has certain characteristics.The combined application of high frequency ultrasound is helpful to improve the diagnostic coincidence rate.
