超声造影对肝脏恶性局灶性病变的诊断价值

目的:探讨超声造影对恶性肝脏局灶性病变的诊断价值。方法:行超声造影的肝脏恶性局灶性占位病变33例,所有患者均进行了增强CT或增强MRI检查,25例经病理证实及随访观察。结果:33例肝脏恶性局灶性病变,包括肝细胞性肝癌23例、胆管细胞癌2例、转移性肝癌6例、门静脉癌栓6例(其中4例继发于肝细胞性肝癌)。肝细胞性肝癌、转移性肝癌和门静脉癌栓具有特征性的超声造影表现,而胆管细胞性肝癌的超声造影表现多样。结论:超声造影对肝脏恶性局灶性病变的诊断具有重要的价值,但对不典型病例,尤其是对胆管细胞性肝癌需进一步检查确诊。

Diagnostic Value of Contrast Enhanced Ultrasound in Malignant Focal Liver Lesion

Objective:To explore the diagnostic value of contrast enhanced ultrasound in malignant focal liver lesion(FLL).Methods:Thirty-three cases with malignant FLL had contrast enhanced ultrasound in our hospital during July 2004 and September 2005.All the patients had contrast enhanced CT or MRI and twenty-five cases were confirmed by pathology.Results:Thirty-three cases with malignant FLL were detected,including 23 hepatocellular carcinomas,2 cholangio carcinomas,6 metastatic tumors and 6 cases metastasis in portal vein(4 cases companied with hepatocellular carcinomas).Hepatocellular carcinomas,metastatic tumors and metastasis in portal vein had characteristic contrast pattern,while cholangio carcinomas had various contrast pattern.Conclusion:Contrast enhanced ultrasound plays an important role in diagnosis of malignant FLL.However,non-typical FLL and especially cholangio carcinomas still need further examination.
