摘　　要：目的探讨二维及彩色多普勒超声在不典型肝脓肿诊断中的价值,并总结不典型肝脓肿的超声图像特点,以提高诊断符合率。方法对42例经病理学检查确诊的不典型肝脓肿患者进行二维超声及彩超检查,总结不典型肝脓肿超声图像特点,并将诊断结果与病理学检查结果相比较。结果二维超声诊断符合率为88.10%,疑诊率7.14%,误诊率4.76%;病灶多呈不均匀的中等回声,肝内可探及不均匀"气体样"强回声,病灶边界不规则,病灶分布不均匀,彩色多普勒血流图像可探及少许血流信号。结论二维超声及彩色多普勒超声可根据回声、血流信号确定不典型肝脓肿位置、大小、形态,具有一定的诊断价值。OBJECTIVE To investigate the value of two-dimensional and color Doppler ultrasound in the diagnosis of atypical liver abscess and summarize the ultrasound image characteristics of atypical liver abscess so as to improve the accordance rate of diagnosis. METHODS The two-dimensional ultrasound and color Doppler ultrasound was employed for 42 cases of patients who were confirmed as the liver abscess by the pathological examination, the characteristics of ukrasound imaging of the atypical hepatic abscess were summarized, and the diagnostic results were compared with the results of the pathological examination. RESULTS The accordance rate of diagnosis of the two-dimensional ultrasound was 88.10%, the suspected diagnosis rate was 7.14%, and the misdiagnosis rate was 4.76%. The lesions showed mostly uneven medium echo, intrahepatic gas-like echo, uneven hyperechoic lesion border, and uneven distribution of lesions, while a few blood flow signals could be detected through the color Doppler imaging. CONCLUSION The two-dimensional ultrasound and color Doppler ultrasound can determine the location, size, and shape of the atypical liver abscess according to the echo and blood flow signals and has a certain diagnostic value.
