Pneumatosis (cystoides) intestinalis is defined as the presence of gas in the bowel wall and can be found anywhere in the gastrointestinal tract. It may be harmless or life-threatening, depending on the etiology which includes infectious and drug-induced colitis, bowel ischemia and necrotizing enterocolitis. The lesion has additionally been described following endoscopy. We report two cases of asymptomatic pneumatosis coli mimicking polyposis syndrome or malignancy. Both cases were verified histologically after snare polypectomy or hemicolectomy. The differential diagnosis and the clinical significance of the disease are discussed. Accurate diagnosis, which is mainly based upon endoscopy, computed tomography and histology, is crucial for optimal patient management thus avoiding unnecessary surgical procedures.
肠气肿（囊状）被定义为肠壁内存在气体，可以在胃肠道的任何部位发现。它可能是无害的，也可能是危及生命的，这取决于病因，包括感染性和药物诱导性结肠炎、肠缺血和坏死性小肠结肠炎。该病变还在内镜检查后被描述。我们报告了两例无症状的结肠气肿，类似于息肉病综合征或恶性肿瘤。这两个病例在圈套息肉切除术或半结肠切除术之后都通过组织学得到了证实。讨论了该病的鉴别诊断和临床意义。准确的诊断，主要基于内镜、计算机断层扫描和组织学，对于最佳的患者管理至关重要，从而避免不必要的手术。
