Abstract:
Objective To investigate the value of ultrasound contrast in differential diagnosis of liver alveolar hydatid disease and hepatic malignant tumor.Method Totally 36 cases of liver alveolar hydatid disease and 31 cases of hepatic malignant tumor were retrospectively analyzed,who visited the Ultrasound Department of Qinghai Red Cross Hospital from March 2010 to September 2013,the performance characteristics of gray-scale ultrasound and contrast-enhanced ultrasound (CEUS) on hepatic malignant tumor and liver alveolar hydatid disease were compared.Results Gray-scale sonography of 36 liver alveolar hydatid diseases showed clear boundary,heterogeneous hypoechoic nodules,and the maximum area was (5.06 ± 2.46) cm2 in 49 lesions;gray-scale sonography of 31 hepatic malignant tumors showed unclear boundary,hypoechoic nodules,and the maximum area was (7.29 ± 5.83) cm2.CEUS of liver alveolar hydatid disease showed non-enhancement in three phases,and rim enhancement was seen synchronized with the liver parenchyma.CEUS of hepatic malignant tumor showed hyperenhancement in arterial phase,equal-enhancement or hypo-enhancement in portal phase and delayed phase,and abnormal perfusion areas were clear.Conclusion Liver alveolar hydatid disease is different in the performance of CEUS from hepatic malignant tumor,CEUS has a great value in the differential diagnosis of liver alveolar hydatid disease and hepatic malignant tumor.
