目的:探讨局限型胆囊腺肌增生症(gallbladder adenomyomatosis)的超声影像学特征。方法:回顾性分析2014年2月至2017年3月经手术病理确诊的30例局限型胆囊腺肌症的病例资料,分析其超声二维声像图特征。结果:30例局限型胆囊腺肌增生症中28例(93.1%)病灶位于胆囊底部,29例( 96.7%)为宽基底,28例(93.1%)为低回声或中等回声,29例( 96.7%)病灶处胆囊内壁连续性完整,21例(70%)病灶内可见囊样无回声区,12例(40%)病灶内可见点状强回声伴彗尾征,28例(93.1%)未见明显彩色血流信号。联合应用高频超声共正确诊断21例,诊断符合率为70.0%。结论:局限型胆囊腺肌增生症超声二维声像图具有一定特征性,联合应用高频超声有助于提高诊断符合率。 |

Abstract: |
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. |
