Intestinal pneumatosis (IP) is an infrequent radiological sign defined as pathological gas infiltration into the bowel wall. It may be associated to different underlying clinical conditions-inflammatory bowel diseases, malignancies, chemotherapy, infections, immune deficiency status, trauma, intestinal ischemia, and necrosis-that are often related to emergency state and require a prompt diagnosis. All the imaging techniques, especially abdominal radiography and Computed Tomography, could detect the presence of IP and discern the forms related to emergency conditions. The differential diagnosis is essential to start an immediate clinical or surgical management and treatment. The aim of this article is to review the radiological features of IP in different illnesses, with particular attention to differential diagnosis.
肠壁积气（IP）是一种罕见的影像学表现，定义为病理性气体侵入肠壁。它可能与不同的潜在临床状况相关，如炎症性肠病、恶性肿瘤、化疗、感染、免疫缺陷状态、创伤、肠缺血和坏死等，这些情况通常与紧急状态相关，需要及时诊断。所有的影像学检查技术，尤其是腹部X线摄影和计算机断层扫描，都可以检测到IP的存在，并辨别与紧急情况相关的形式。鉴别诊断对于立即开始临床或手术管理及治疗至关重要。本文的目的是回顾不同疾病中IP的影像学特征，尤其关注鉴别诊断。
