Analysis of ultrasonography features of localized gallbladder adenomyomatosis

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.
