肝泡状棘球蚴病的超声及病理表现

Sonographic and pathological presentations of hepatic alveolar echinococcosis

目的:分析肝泡状棘球蚴病患者的临床、病理及超声图像特征.方法:回顾性分析2002-2007年我院经手术病理证实的肝泡状棘球蚴病患者15例的超声图像特征并分型.结果:15例肝泡状棘球蚴病单发12例,多发3例,共发现肿块20个;超声特征:多位于左肝,大小多为5cm以上,形态多不规则,边界多清晰,内部回声多呈高回声、不均匀、无液化、无钙化,后方回声多衰减,无声晕、无内部血流多见,未见肝门及腹腔淋巴结肿大;根据声像图特征分为:实性肿块型(13个,65%)、肿块液化型(7个,35%)、肿块钙化型(8个,40%).结论:超声检查肝泡球蚴病超声影像具有特征性,是肝泡球蚴病重要的影像学检查方法.

AIM： To analyze the ultrasonographic and pathological features of patients with the hepatic alveolar echinococcosis. METHODS： The sonograms of 15 cases of the hepatic alveolar echinococcosis from 2002 to 2007 in our hospital were retrospectively reviewed. RESULTS： Solitary lesions were found in 12 cases, multiple lesions were found in 3 cases. The total 20 lesions were classified into 3 subtypes of different ultrasound features： solid lesions （13 cases, 65%）, partially liquefied solid lesions （7 cases, 35%） and solid lesions with liquefaction and calcification （8 cases, 40%）. CONCLUSION： The ultrasound manifestation of the hepatic alveolar echinococcosis is specific and ultrasonography is a useful imaging diagnostic tool.
