摘要
目的探讨实时超声造影相较于常规B型超声和彩色多普勒超声对肝泡型包虫病的鉴别诊断价值。方法回顾性分析经常规超声误诊、错诊和漏诊的肝泡型包虫病52例,全部采用实时超声造影对病灶动脉相、门脉相和延迟相进行扫描,并经病理确诊。结果 42例肝泡型包虫病,均表现为造影全程负显影,显著区别于其他肝内实性或囊实性占位病变的超声造影表现。结论与常规超声相比,实时超声造影检查能显示肝脏病变的血管分布及时相特征,为肝泡型包虫病的诊断和鉴别诊断提供了一种更准确的检查方法。
Objective To investigate the differential diagnosis of hepatic alveolar echinococcosis by real time contrast-enhanced ultrasound by comparison to B-mode and color Doppler.Methods Fifty-two cases of hepatic alveolar echinococcosis misdiagnosed,error diagnosed and missed diagnosed by conventional ultrasound were analyzed retrospectively,all patients were scanned by real time contrast-enhanced ultrasound during arterial,portal-venous and delayed liver phase.The results were confirmed by pathology.Results Forty-two cases were confirmed to be hepatic alveolar echinococcosis,all of them showed no enhancement throughout three phases.The manifestation was significantly distinguished with other solid or cyst-solidary tumors.Conclusion Compared to conventional sonography,real time enhanced ultrasound markedly improves the diagnostic accuracy and differential diagnosis of hepatic alveolar echinococcosis by displaying the vasculature distribution and phase characteristic of these lesions.
