OBJECTIVE
We aim to determine the efficiency of CT in identification of cystic echinococcosis in sheep.
METHODS
Fifty-three sheep with liver cysts confirmed by ultrasonography were subject to CT scan to evaluate the number, size, and type of the cysts in liver and lung, confirmed using necropsy. The correlation of numbers between liver cysts and lung cysts was calculated using Pearson analysis.
RESULTS
Necropsy indicated a 98% consensus on size, location, number, and activity compared with CT scan. The viable cysts were 53.1% and 50.6% in the liver and lung, respectively. Among the cysts in liver, 35.5%, 9.5%, 5.7%, 10.2%, and 39.1% were Types CE1, CE2, CE3, CE4, and CE5, respectively. The cysts in the lungs, 17.4%, 26.9%, 12.1%, 11.6%, and 32.1%, were Types CE1, CE2, CE3, CE4, and CE5, respectively. A significant correlation was noticed between the number of cysts in liver and those in lung ( = 0.770, < 0.001).
CONCLUSIONS
CT scan is a suitable tool in determining the size and type of cystic hydatid cysts in both liver and lung of sheep. A significant correlation was noticed between the numbers in liver and lung, indicating that lung infection was likely due to the expansion of liver cyst burden pressure.
目的
本研究旨在评估 CT 对绵羊肝包虫病的诊断效能。
方法
对 53 例经超声检查证实为肝包虫病的绵羊进行 CT 扫描，以评估肝、肺内囊肿的数量、大小和类型，并通过剖检进行确认。采用 Pearson 分析计算肝囊肿和肺囊肿数量之间的相关性。
结果
与 CT 扫描相比，剖检在大小、位置、数量和活动度方面具有 98%的一致性。在肝和肺中，活的包虫囊肿分别为 53.1%和 50.6%。在肝内囊肿中，CE1、CE2、CE3、CE4 和 CE5 型分别占 35.5%、9.5%、5.7%、10.2%和 39.1%。在肺内囊肿中，CE1、CE2、CE3、CE4 和 CE5 型分别占 17.4%、26.9%、12.1%、11.6%和 32.1%。肝内囊肿数量与肺内囊肿数量之间存在显著相关性（ = 0.770， < 0.001）。
结论
CT 扫描是一种确定绵羊肝、肺内包虫囊肿大小和类型的有效工具。肝、肺内囊肿数量之间存在显著相关性，提示肺感染可能是由于肝囊肿负荷压力增加所致。
