摘要
目的:探讨原发性胃淋巴瘤的CT表现及诊断价值。方法:对23例经手术或病理活检证实的原发性胃恶性淋巴瘤的CT资料进行回顾性分析。结果:原发性胃恶性淋巴瘤按CT表现分胃壁弥漫增厚型、节段增厚型、局限肿块型、多发结节型4型。较有特征性CT表现为:①胃壁增厚显著(多>2cm),受累范围广(多>50%),多灶性分布;②受累胃壁外缘光滑清晰,无明显外侵征象;③黏膜粗大,受累胃壁及胃腔大小形态具有轻微可变性;④增强扫描黏膜呈细线样持续强化;⑤不伴有胃周淋巴结增大的肾门水平腹膜后淋巴结肿大。结论:CT检查对原发性胃恶性淋巴瘤的诊断及鉴别诊断有重要价值。
Objective：To evaluate the value of CT in the diagnosis of primary gastric malignant lymphoma. Methods： 23 cases of primary gastric malignant lymphoma proved by operation and pathology were retrospectively reviewed. Results： Primary gastric malignant iymphoma was divided into 4 types by CT appearances. Diffuse thickening; Segmental thickening; Mass of the gastric wall; Multiple nodus. The characteristic of CT manifestations were： ①Gastric wall significant thicken （〉2cm）, the spread involved is extensive;（〉50%）, muli focality distribution; ②Gastric wall were smooth contour without invasion of nearby organs;③Mucosa enlargement, soft gastric wall and gastral cavity had slight changeability;④Linear enhancement of gastric mucosa on enhancement scanning; ⑤Retroperitoneal renal hilus level lymphadenovarix without perigastric lymphadenovarix. Conclusion：CT has significant value in the diagnosis and differential diagnosis of primary gastric malignant lymphoma.
