A, There is a large, polypoid filling defect in the antrum of the stomach that displaces the barium around it (solid black arrow). Contained within the mass and seen en face is an irregularly shaped collection of barium that represents an ulceration in the mass (dotted black arrow). This was an adenocarcinoma of the stomach.

（A）胃窦部可见一大的息肉样充盈缺损，把钡剂挤压至周围。肿块正面观可见其内含钡剂，边缘不规则，提示肿块内部有溃疡。这是一例胃腺癌。

B, The entire body of the stomach displays a lack of distensibility, losing the normal ballooning outward that every portion of the GI tract demonstrates when filled with enough barium or air. Instead, the walls of the stomach are concave inward (solid white arrows) and rigid, a sign of malignancy. This stomach would display the same appearance on all images. This is the typical appearance for linitis plastica, caused by an infiltrating adenocarcinoma of the stomach.

（B）整个胃体未见扩张，失去了正常的膨胀外观。正常消化系统空腔脏器充满钡剂或气体时应该是膨胀的。还可见胃壁向内凹陷，僵硬，提示是恶性的征象。在所有切面都表现为这一征象。这是典型的“皮革胃”，由于浸润性胃腺癌导致。
