胃淋巴瘤的CT诊断

CT Diagnosis of Gastric Lymphoma

目的：探讨胃淋巴瘤的ＣＴ表现及其诊断价值。材料和方法：回顾性分析１１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：１１例胃淋巴瘤中原发性６例、继发性３例，初诊时即属ＩＶ期者２例，病变的ＣＴ表现可分为三种类型：胃壁弥漫增厚型８例（７２．７％），节段增厚型２例（１８．２％），肿块型１例（９．１％）；平均厚度约３．１ｃｍ（１．６ｃｍ－６．０ｃｍ）。病灶边界清晰光整，增强后病灶呈轻度强化，病灶内表面胃粘膜呈明显线样强化，均无周围浸润。结论：胃淋巴瘤的ＣＴ表现有一定的特征，有助于诊断。

Purpose:To evaluate the value of CT in the diagnosis of gastric lymphoma.Materials and Methods:CT scans and clinical data of 11 gastric lymphoma (6 primary,3 secondary,and 2 of stage IV diagnosed at the beginning)were retrospectively reviewed.Results:3 types of lesions were found on CT:diffuse thickening(n=8,72.7%),segmental thickening (n=2,18.2%),and mass(n=1,9.1%)of the gastric wall.Mean thickness of gastric wall was 3.1cm(1.6cm-6.0cm).The lesions had clear smooth contour, slight contrast enhancement and linear enhancemennt of gastric mucosa on the inner surface without invasion of nearby organs.Conclusion:Gastric lymphoma has characteristic CT fingings helpful to the diagnosis.
