The peritoneum is a unique serosal membrane, which can be the site of primary tumors and, more commonly, secondary pathologic processes. Peritoneal carcinomatosis is the most common malignant condition to affect the peritoneal cavity, and the radiologist plays an important role in making the diagnosis and assessing the extent of disease, especially in sites that may hinder surgery. In this review, we address the role of the radiologist in the setting of peritoneal pathology, focusing on peritoneal carcinomatosis as this is the predominant malignant process, followed by revising typical imaging findings that can guide the differential diagnosis.We review the most frequent primary and secondary peritoneal tumor and tumor-like lesions, proposing a systemic approach based on clinical history and morphological appearance, namely distinguishing predominantly cystic from solid lesions, both solitary and multiple.
腹膜是一种独特的浆膜，它可以是原发性肿瘤的部位，更常见的是继发性病理过程。腹膜转移癌是最常见的恶性疾病，影响腹膜腔，放射科医生在做出诊断和评估疾病程度方面发挥着重要作用，特别是在可能妨碍手术的部位。在这篇综述中，我们探讨了放射科医生在腹膜病变中的作用，重点介绍了腹膜转移癌，因为这是主要的恶性过程，其次是复习可以指导鉴别诊断的典型影像学表现。我们回顾了最常见的原发性和继发性腹膜肿瘤和肿瘤样病变，根据临床病史和形态学表现提出了一种系统的方法，即区分主要为囊性和实性病变，包括单发和多发。
