肝泡状棘球蚴病的声像图特征及与肝癌的鉴别诊断

Ultrasound appearance of hepatic alveolar echinococcosis and differentiaton of hepatocellular carcinoma

目的 探讨肝泡状棘球蚴病 (HAE)的声像图特征及与原发性肝癌 (HCC)的鉴别诊断 ,以提高超声对HAE的诊断符合率。方法 回顾总结 87例HAE的声像图特征 ,与病理组织类型比较分类 ,结合彩色多普勒能量显像 (CDE) ,提出鉴别要点。结果 87例经手术病理证实的HAE声像图表现为实质肿块型 48例占 5 5 .2 % ,混合型 2 4例占 2 7.6% ,囊样液化型 15例占 17.2 % ,本组诊断符合率为 88.5 % (77/ 87) ,误诊率为 11.5 % (10 / 87)。结论 超声显像对HAE具有较大的诊断价值 。

Objective This study was designed to find the of ultrasound feature of hepatic alveolar echinococcosis(HAE) for better diagnosis and differentiation of hepatocellular carcinoma(HCC). Methods The imaging characteristics of 87HAE cases were reviewed and compared with histopathology,combinative the role of color Doppler energy(CDE). The differentiation criteria were set up. Results 87 cases with HAE were confirmed by operation and pathology.Among the patient population, there were 48 cases of substantial mass type,24 cases with mixed type,15 cases with cystoidfluid type.The overall diagnostic accuracy was 88.5%(77/87). Conclusion Ultrasonography is helpful in the diagnosis of HAE,but differentiation with HCC should be take in consideration.
