目的 通过对四川藏区包虫病的调查 ,分析B超图像特征及其在两型包虫病诊断学上的意义。方法 以便携式B超诊断仪对随机抽样的 3 999人进行腹部实质性脏器B超检查并按照国际分类标准进行超声图像分型。结果 超声检查异常 15 6人 ,根据图象判断细粒棘球蚴病 (CysticHydatidDiseasesCHD)患者 76人 (1.9% ) ,泡球蚴病 (AlveolarHydatidDisease,AHD)患者 76人 (1.9% )。结论 CHD中Ⅱ、Ⅲ、Ⅳ及AHD包块中心液化坏死的“熔岩”征图像具有特征性诊断意义 ,但两型包虫病早期诊断仅仅依赖超声图像无法判断 ,需结合血清学等检测手段方可确诊。超声图像国际分类标准在现场流行病学调查中具有极其重要的使用价值。
Objective To investigate the characteristics of ultrasound image and its significance in the diagnosis of two types of hydatid disease through the investigation of echinococcosis in the Tibetan area of Sichuan Province. Methods A total of 3 999 randomly selected patients underwent B ultrasound examination of the abdomen with a portable B ultrasound diagnostic apparatus and performed ultrasound image classification according to the international classification standards. Results There were 16 abnormalities (1.9%) in 76 patients (1.9%) with alveolar hydatidosis (AHD) according to the images and 156 patients with abnormalities of cystic hydatidosis. Conclusion The “lava” sign of liquefaction and necrosis in centers of Ⅱ, Ⅲ, Ⅳ and AHD in CHD is characteristic of diagnostic significance. However, the early diagnosis of hydatidiform encephalopathy can not be judged by ultrasound alone. Can be diagnosed. The international classification standard of ultrasound images has extremely important use value in field epidemiological investigation.
