目的提高胃淋巴瘤的CT诊断正确率。方法回顾性分析10例经手术或活检病理证实的胃非何杰金淋巴瘤的临床和CT检查资料。结果10例胃淋巴瘤均为原发性。病变CT表现为胃壁弥漫增厚型5例,局限性增厚型4例,肿块型1例。4例发现累及周围脏器,并有淋巴结转移。其中一例仅肾门水平以下腹膜后淋巴结转移。结论胃淋巴瘤的CT表现有一定的特征性,有助于诊断,但有时与胃癌鉴别困难,尚需与其他检查结合以利于提高诊断正确率。
Objective To improve the accuracy of CT diagnosis of gastric lymphoma. Methods The clinical and CT findings of 10 cases of gastric non-Hodgkin’s lymphoma confirmed by surgery or biopsy were analyzed retrospectively. Results 10 cases of gastric lymphoma were primary. CT lesions showed diffuse gastric thickening in 5 cases, 4 cases of localized thickening, mass in 1 case. 4 cases found to involve the surrounding organs, and lymph node metastasis. One case of renal cell carcinoma only below the level of retroperitoneal lymph node metastasis. Conclusion The CT findings of gastric lymphoma have certain characteristics, which are helpful for diagnosis. However, sometimes it is difficult to differentiate gastric cancer from gastric cancer, so it is still necessary to combine with other tests to improve the diagnostic accuracy.
