RESUMO
Although pathologies affecting stomach are commonly encountered in computed tomography imaging of the abdomen, they are frequently overlooked. Their etiologies are often diverse; however, most of them have certain well-documented imaging characteristics. Conventionally the stomach abnormalities were classified according to their etiopathogenesis. This article aims at providing the readers with an easy approach by categorizing abnormalities of stomach using a novel image appearance-based classification. An attempt to illustrate various gastric pathologies using this new classification by means of pictorial examples is made. Basic computed tomography imaging anatomy of the stomach and imaging techniques that need to be adapted are also emphasized in the outset of the discussion.
