摘要
多种浸润性疾病会影响小肠，通常会导致弥漫性小肠壁增厚。这些浸润性疾病可以表现出各种因素，例如免疫或肿瘤细胞的涌入，或者在肠壁的一个或多层中积累物质的积累。尽管在横截面图像上的浸润性疾病的出现可能存在很大的重叠，但对更具体的辅助成像特征和临床病理相关性的全面了解可以显着范围缩小鉴别诊断。放射科医生可以在综合临床和成像信息并引导随后的工作中发挥作用。作者对通常涉及小肠的浸润性疾病进行了全面评论。这些疾病是基于其病理生理特征组织的，其中有多个说明性案例，以增强对这些实体的理解。 CT和MRI目前是评估小肠病的最常用成像方式，该综述侧重于这两种方式。提供了有关这些浸润性疾病的病理特征，临床表现和成像发现的详细信息，以帮助放射科医生识别和区分这些疾病。
Abstract
Multiple infiltrative disorders can affect the small bowel, often resulting in diffuse small bowel wall thickening. These infiltrative disorders can manifest owing to various factors such as an influx of immunologic or neoplastic cells or the accumulation of substances within one or more layers of the intestinal wall. Although there can be considerable overlap in the appearances of infiltrative diseases on cross-sectional images, a comprehensive understanding of more specific ancillary imaging features and clinicopathologic correlation can substantially narrow the differential diagnosis. The radiologist can be instrumental in synthesizing the clinical and imaging information and guiding subsequent workup. The authors present a comprehensive review of the infiltrative disorders that commonly involve the small bowel. These disorders are organized on the basis of their pathophysiologic features, with multiple illustrative case examples to enhance understanding of these entities. CT and MRI are currently the most commonly used imaging modalities for evaluating small bowel disorders, and this review is focused on these two modalities. Detailed information regarding the pathologic features, clinical presentation, and imaging findings of these infiltrative disorders is provided to aid radiologists in recognizing and differentiating these conditions.
