【摘要】：目的本文旨在分析肝肺吸虫病的超声造影临床特征,探讨超声造影对肝肺吸虫病的诊断及鉴别诊断价值。方法经手术病理或穿刺活检证实的肝肺吸虫病及肝脓肿、肝内胆管细胞肝癌(ICC)各20例,回顾性总结分析3组病例的临床资料、常规灰阶超声特征及超声造影增强特点。结果超声造影动脉期-门脉/延迟期呈高-低增强的比例分别为30%、60%及85%,呈三期低增强的比例分别为20%、15%及5%,门脉/延迟期消退比例分别为50%、75%及90%,差异有统计学意义(P0.05);病灶增强范围:均以部分增强为主,3组间无明显差异(P0.05);病灶内增强区特征:肝肺吸虫病及肝脓肿以均匀环状为主(50%、65%),ICC组以不规则环状为主(60%);坏死区特征:肝肺吸虫以不规则窦道样为主(60%),肝脓肿以筛孔样为主(60%),上述差异均有统计学意义(P0.05);肝肺吸虫病组坏死区呈不同程度的不规则窦道样改变(60%),较其余2组差异显著(P0.05)。结论超声造影后仔细观察病灶内坏死区形态及病灶周边增强特征,同时结合临床资料,可明显提高对肝肺吸虫病的诊断及鉴别诊断能力。
[Abstract]:Objective to analyze the clinical features of hepatic paragonimiasis and to explore the value of contrast-enhanced ultrasonography in the diagnosis and differential diagnosis of hepatic paragonimiasis. Methods Hepatic paragonimiasis and liver abscess were proved by pathology or biopsy. 20 cases of intrahepatic cholangiocarcinoma (ICC) were analyzed retrospectively and the clinical data of 3 groups were analyzed retrospectively. Results the proportion of high-low enhancement in arterial phase-portal vein / delayed phase was 30% and 85% respectively. The proportion of low enhancement in phase 3 was 20 15% and 5% respectively. The extinction rates were 50% and 90%, respectively. The difference was statistically significant (P 0.05); the range of focus enhancement: there was no significant difference among the three groups: there was no significant difference among the three groups; the characteristics of the enhancement zone in the focus were as follows: hepatic paragonimiasis and liver abscess were mainly homogenized in 50% and 65% in ICC group. The characteristics of the necrotic zone are as follows: the liver paragonimiasis is irregular sinusoid and the liver abscess is mainly composed of ethmoidal foramen. All the above differences are statistically significant (P 0.05); the necrotic areas in the paragonimiasis group are irregular sinus in different degrees. Compared with the other two groups, there was a significant difference between the two groups (P0.050.Conclusion after contrast-enhanced ultrasonography, the morphology of the necrotic area and the enhancement characteristics around the lesion were observed carefully. Combined with clinical data, the ability of diagnosis and differential diagnosis of hepatic paragonimiasis can be improved obviously.
