The sonographic images obtained from 17 patients with gastric lymphoma were reviewed. In 15/17 cases the tumor presented as an abdominal mass, either with a "target-like" pattern or with a solid, homogeneous structure; in the remaining two cases only thickening of portions of the gastric wall was seen. Two features that may help to differentiate lymphoma from other gastric diseases were observed in patients of this series. In eight cases thickened mucosal folds could be identified within the gastric mass, outlined by strong luminal echoes arranged like the spokes of a wheel. A hypoechoic appearance of hte infiltrated gastric wall was seen in 13/17 cases; it was less echogenic than the adjacent liver parenchyma and, often, it was almost echo-free. Sonography is often used as the first imaging method in cases of patients with abdominal complaints and clinically unsuspected tumors of the stomach may be visualized first by it. In such cases, identification of these features within a gastric mass may allow sonography to suggest the lymphomatous nature of the disease.
对17例胃淋巴瘤患者的超声图像进行了回顾性分析。17例中有15例肿瘤表现为腹部肿块，呈“靶样”模式或实性均匀结构；其余2例仅见胃壁部分增厚。本系列患者中观察到两个有助于将淋巴瘤与其他胃部疾病区分开来的特征。8例胃肿块内可识别出增厚的黏膜皱襞，由像车轮辐条一样排列的强腔内回声勾勒出轮廓。17例中有13例可见浸润胃壁呈低回声；其回声低于相邻的肝实质，且通常几乎无回声。超声检查常被用作有腹部不适患者的首选成像方法，临床上未怀疑的胃肿瘤可能首先通过超声检查发现。在这种情况下，在胃肿块内识别出这些特征可能使超声检查提示该病的淋巴瘤性质。
