肺淋巴瘤样肉芽肿的CT特征

The CT charateristics of lymphomatoid granulomatosis of the lung

目的:研究肺淋巴瘤样肉芽肿的CT诊断价值。方法:回顾分析17例经手术或穿刺活检病理证实的肺淋巴瘤样肉芽肿的CT表现。结果:17例肺淋巴瘤样肉芽肿的CT表现分为4种类型:①类肺炎型3例,表现为两肺大片状密度增高影,其中2例病灶内可见含支气管的气象;②肿块型5例,表现为两肺多发大小不等的不规则肿块;③结节型4例,表现为两肺多发大小不等的结节(小于3cm);④混合型5例,表现为两肺大片状密度增高影及不规则肿块或结节影。17例中3例出现肺门、纵隔淋巴结肿大,4例伴有胸腔积液。结论:CT对各种类型的肺淋巴瘤样肉芽肿有一定的诊断价值,但最终确诊仍需依靠活检病理。

Objective：To study the CT charateristics of lymphomatoid granulomatosis of the lung.Methods：The CT features in 17 patients with lymphomatoid granulomatosis of the lung confirmed by pathology were retrospectively analyzed. Results：The CT findings of 17 patients with lymphomatoid granulomatosis were classified into 4 types：① Pneumonia-like type （3 cases）,CT showed larger areas of high opacities in bilateral lung. Air-bronchograms was found in 2 cases;② Mass-like type （5 cases）,CT showed multiple irregular masses in bilateral lung;③ Nodular-like type （4 cases）,CT showed multiple nodular opacities in bilateral lung （ 3.0 cm） and ④ Mixed type （5 cases）,CT showed high density opacities and mixed multiple irregular masses or multiple nodular opacities in bilateral lung. 3 of the 17 cases appeared swelled lymph nodes,which can be seen in hilus and mediastinum. 4 of the 17 cases had hydrothorax. Conclusion：The CT characteristics of lymphomatoid granulomatosis of the lung might be of great value for the diagnosis. The final diagnosis,howerer,should be based on pathology.
