The ascaris is a common human parasite and has a world wide distribution. In areas where it is endemic, biliary complications are common. In our locality it occurs mainly in children, presenting with upper abdominal colicky pain usually without jaundice. We have analyzed the positive roentgenological findings of 67 cases which presented in one year. The findings on cholangiography are diagnostic. The worm is seen as a linear translucent filling defect in a dilated common bile duct. Usually it is only faintly outlined by thin tram lines and occasionally there may not be excretion of the contrast material. The attention of radiologists is brought to this condition and the appearances of ascariasis infestation of the intestines are also noted.
蛔虫是一种常见的人体寄生虫，分布于世界各地。在蛔虫流行地区，胆道并发症很常见。在我们当地，蛔虫主要发生在儿童身上，表现为上腹部绞痛，通常无黄疸。我们分析了一年内67例患者的阳性影像学检查结果。胆管造影的表现具有诊断意义。在扩张的胆总管中，蛔虫表现为线状半透明充盈缺损。通常它仅由细的轨道线模糊勾勒出轮廓，偶尔造影剂可能无法排出。提醒放射科医生注意这种情况，同时也注意蛔虫感染肠道的表现。
