Case reports of five patients with pneumatosis intestinalis diagnosed by computed tomography (CT) are presented. Etiology, differential diagnoses, and clinical consequences arising from CT imaging are discussed. In four of the patients, pneumatosis was found to be secondary to gastric ulcer, colon carcinoma, metastasis in the mesentery, and trauma-induced mesenteric ischemia. In one patient, the etiology remained elusive. Using CT, both the extent and the distribution pattern of pneumatosis could be depicted, allowing for differentiation of primary and secondary forms and assessment of prognosis. Evaluation with a lung window is a pre-requisite for reliable diagnosis of pneumatosis with CT. The presence of gas in the mesenteric or portal venous system in mesenteric ischemia is indicative of an unfavorable prognosis.
本文介绍了5例经计算机断层扫描（CT）诊断为肠壁积气症患者的病例报告。讨论了病因、鉴别诊断以及CT成像所引发的临床后果。在4例患者中，发现肠壁积气症继发于胃溃疡、结肠癌、肠系膜转移瘤以及创伤性肠系膜缺血。1例患者的病因仍不明确。通过CT能够描绘出肠壁积气症的范围和分布模式，有助于区分原发性和继发性形式并评估预后。使用肺窗进行评估是通过CT可靠诊断肠壁积气症的前提条件。肠系膜缺血时肠系膜或门静脉系统中存在气体提示预后不良。
