Ascaris lumbricoides is the second most common intestinal parasite world-wide and, although the infection can be asymptomatic, in some cases it can present with complications, such as acute pancreatitis.
We describe the case of a 37-year-old man, with a history of travelling in Eastern countries who presented with Ascaris lumbricoides-induced acute pancreatitis mimicking a small pancreatic cancer, diagnosed during an upper EUS. The endoscopy revealeda roundworm floating in the duodenum; its endoultrasonographic appearance showed a diffuse inhomogeneous pattern, with hypoechoic echotexture, such as in acute pancreatitis. Microbiological examination of the worm revealed a 20 cm long Ascaris lumbricoides.
In non endemic countries, acute pancreatitis induced by Ascaris lumbricoides is an unusual diagnosis, and should be suspected especially in patients with history of traveling in endemic areas.
蛔虫是全球第二常见的肠道寄生虫，尽管感染可能无症状，但在某些情况下会出现并发症，如急性胰腺炎。
我们描述了一名37岁男性的病例，该患者有在东方国家旅行的病史，因蛔虫引起的急性胰腺炎就诊，表现类似小胰腺癌，在上消化道超声内镜检查（EUS）时被诊断出来。内镜检查发现一条蛔虫漂浮在十二指肠内；其内镜超声表现为弥漫性不均匀模式，回声质地低回声，类似急性胰腺炎。对蛔虫的微生物学检查发现是一条20厘米长的蛔虫。
在非流行国家，由蛔虫引起的急性胰腺炎是一种不常见的诊断，特别是有在流行地区旅行史的患者应怀疑此病。
