Abstract

Over one billion people worldwide are affected by Ascaris lumbricoides. While ascariasis is rare in Saudi Arabia, it is occasionally encountered among expatriates from endemic regions. We report a case of biliary ascariasis in a 29-year-old female expatriate, highlighting the clinical, laboratory, radiological, and endoscopic retrograde cholangiopancreatography (ERCP) findings, with particular emphasis on the diagnostic role of imaging. The patient presented to the emergency department with right upper quadrant abdominal pain, although physical examination was unremarkable. Abdominal ultrasound revealed diffuse dilatation of the intra- and extrahepatic biliary tree, with a long, mobile, echogenic structure within the common bile duct, lacking acoustic shadowing. Magnetic resonance cholangiopancreatography (MRCP) confirmed the presence of intraductal Ascaris extending into the intrahepatic ducts. The patient was started on antiparasitic therapy and had an uneventful recovery. This case underscores the essential role of imaging in diagnosing biliary ascariasis, particularly when clinical and laboratory findings are nonspecific.

胆道蛔虫病在非流行地区：1例报告

全世界有超过10亿人受到类蛔虫的影响。虽然蛔虫病在沙特阿拉伯很少见，但偶尔会在来自流行地区的外籍人士中遇到。我们报告一例29岁外籍女性胆道蛔虫病，强调临床、实验室、放射学和内窥镜逆行胆管胰胆管造影（ERCP）的发现，特别强调影像学的诊断作用。患者以右上腹腹痛就诊于急诊科，但体格检查无明显异常。腹部超声显示肝内和肝外胆道弥漫性扩张，胆总管内有长而可移动的回声结构，无声影。磁共振胆管造影（MRCP）证实导管内蛔虫延伸至肝内管。病人开始接受抗寄生虫治疗，恢复得很顺利。本病例强调了影像学在诊断胆道蛔虫病中的重要作用，特别是当临床和实验室结果非特异性时。
