The radiographic features of 20 cases of pathologically confirmed heterotopic pancreatic rests involving the stomach were analyzed. Aberrant pancreatic tissue in the stomach produces a broader spectrum of radiographic findings than had been thought. The mass produced by the aberrant tissue is often larger and more sessile than usually anticipated, and may simulate a mural neoplasm or adenomatous polyp. While most cases occur in the distal antrum or prepyloric area, some occur in the more proximal portion of the antrum. Less than half of the cases in this series included the finding of a small central niche. When a niche was present, it was often large in relation to the mass, and simulated a gastric ulcer or ulcerating neoplasm.
对20例经病理证实的累及胃的异位胰腺残余灶的影像学特征进行了分析。胃内的异位胰腺组织产生的影像学表现比以往认为的更为广泛。异位组织产生的肿块通常比预期的更大且更具蒂，可能类似壁内肿瘤或腺瘤性息肉。虽然大多数病例发生在胃窦远端或幽门前区，但有些发生在胃窦更近端的部分。本系列中不到一半的病例发现有小的中央龛影。当存在龛影时，其相对于肿块往往较大，类似胃溃疡或溃疡性肿瘤。
