The main endemic areas for alveolar echinococcosis (AE) are in Central Europe and Western China, and in >98% of cases, AE manifests in the liver. The aim of this work was to compare European and Chinese patient groups for number, size, and computed tomography (CT) appearance of hepatic AE lesions. A total of 200 CT scans of patients with hepatic AE were evaluated by four blinded, experienced radiologists from two European (Besancon, Ulm) and two Chinese centres (Xining, Urumqi). In addition to noting the number, size, and localisation of the lesions, the radiologists evaluated morphological appearance using the Ulm Classification - CT scheme. Chinese patients were younger than European patients (36.8 ± 13.2 vs. 63.5 ± 17.7; < 0.0001) and had significantly larger lesions (120.4 ± 50.8 vs. 70.9 ± 39.8; p < 0.0001). The morphological appearance of the lesions on CT differed significantly between the two groups ( < 0.05), as did the number of lesions (2.6 ± 3.9 in European centres versus 3.8 ± 5.0 in Chinese centres; = 0.0062). Patient age and AE-related morphological manifestations differ between Europe and China, but the reasons for the differences are unknown.
泡型包虫病（AE）的主要流行地区在中欧和中国西部，且在98%以上的病例中，AE表现于肝脏。本研究的目的是比较欧洲和中国患者群体肝AE病灶的数量、大小及计算机断层扫描（CT）表现。来自两个欧洲中心（贝桑松、乌尔姆）和两个中国中心（西宁、乌鲁木齐）的四名经验丰富的放射科医生对200例肝AE患者的CT扫描进行了盲法评估。除记录病灶的数量、大小和位置外，放射科医生还使用乌尔姆分类 - CT方案评估了形态学表现。中国患者比欧洲患者年轻（36.8±13.2岁 vs. 63.5±17.7岁；<0.0001），且病灶明显更大（120.4±50.8 vs. 70.9±39.8；p<0.0001）。两组CT上病灶的形态学表现差异显著（<0.05），病灶数量也不同（欧洲中心为2.6±3.9个，中国中心为3.8±5.0个；=0.0062）。欧洲和中国患者的年龄及与AE相关的形态学表现存在差异，但差异原因尚不清楚。
