We report herein an unusual case of primary mesosigmoidal hydatid cyst that presented as acute left colonic obstruction mimicking sigmoid colon cancer. A 61-year-old man with a 3-day history of abdominal pain, distention, obstipation, vomiting, and fever was admitted to the emergency department of our hospital. Surgery was performed under a presumptive diagnosis of acute left colonic obstruction. The intraoperative findings were highly suggestive of sigmoid colonic carcinoma and Hartmann's procedure was performed. Histopathological examination of the pathological specimen revealed an isolated hydatid cyst embedded in mesosigmoid which had caused mechanical sigmoidal obstruction. Primary extrahepatic, intra-abdominal localization of a hydatid cyst is not unusual. Therefore, as a hydatid cyst may cause a wide variety of clinical syndromes, it should be kept in mind in the differential diagnosis of mechanical bowel obstruction, especially in endemic regions.
我们在此报告一例罕见的原发性乙状结肠系膜包虫囊肿病例，该病例表现为急性左半结肠梗阻，酷似乙状结肠癌。一名61岁男性，有3天的腹痛、腹胀、便秘、呕吐和发热病史，被收入我院急诊科。在急性左半结肠梗阻的初步诊断下进行了手术。术中发现高度提示乙状结肠癌，并进行了哈特曼手术。病理标本的组织病理学检查显示，一个孤立的包虫囊肿包埋在乙状结肠系膜中，导致了机械性乙状结肠梗阻。肝外、腹腔内原发性包虫囊肿并不罕见。因此，由于包虫囊肿可能导致多种临床综合征，在机械性肠梗阻的鉴别诊断中应予以考虑，尤其是在流行地区。
