超声造影检查对肝脏复杂囊性病变的诊断价值

VALUE OF CONTRAST-ENHANCED ULTRASOUND IN THE DIAGNOSIS OF COMPLEX CYSTIC FOCAL LIVER LESIONS

目的探讨超声造影检查在诊断肝脏复杂囊性病变中的应用价值。方法回顾性分析在我院就诊的56例病人(56个病灶)肝脏复杂囊性病变的常规超声及超声造影表现。结果56个病灶常规超声表现为多房囊性25个,囊实性21个,类囊性10个。40个病灶行超声造影检查,其中7个类囊性病灶及3个囊实性病灶呈无增强;17个囊实性、12个多房囊性及1个类囊性病灶的囊壁、分隔及实性部分有不同程度的增强。超声造影诊断肝脏复杂囊性病变良恶性的准确率为88.9%,明显高于常规超声的65.0%,差异有统计学意义(P=0.039)。结论超声造影有助于鉴别肝脏复杂囊性病变的良恶性,表现不典型者可行超声引导下穿刺活检。

Objective To investigate the value of contrast-enhanced ultrasound(CEUS)in the diagnosis of complex cys-tic focal liver lesions.Methods A retrospective analysis was performed for the ultrasound(US)and CEUS images of 56 complex cystic focal liver lesions from 56 patients who attended our hospital.Results Of all 56 lesions,there were 25 multilocular cystic lesions,21 solid-cystic lesions,and 10 cyst-like lesions on US.CEUS was performed for 40 lesions,among which 7 cyst-like lesions and 3 solid-cystic lesions showed no enhancement,while 17 solid-cystic lesions,12 multilocular cystic lesions,and 1 cyst-like lesion showed varying degrees of enhancement in the cyst wall,septa,and solid component.CEUS had a significantly higher accuracy than US in the diagnosis of complex cystic focal liver lesions(88.9% vs 65.0%,P=0.039).Conclusion CEUS can be used to identify benign or malignant complex cystic focal liver lesions,and ultrasound-guided biopsy can be performed for patients with atypical manifestations.
