目的:探讨恶性淋巴瘤的胸部CT表现,及时作出诊断和鉴别诊断。材料与方法:搜集经病理证实的32例胸部恶性淋巴瘤(分为何杰金病和非何杰金淋巴瘤),全部进行CT增强扫描。结果:本组病例中,何杰金病7例,非何杰金淋巴25例,可表现为:(1)纵隔、肺门淋巴结增大,(2)肺部受侵,(3)胸膜病变,(4)心包渗出或胸壁侵犯等。纵隔、肺门淋巴结肿大最为常见。肺部侵犯有四种类型:(1)肿块(结节)型;(2)粟粒型,(3)肺炎型;(4)间质型。最常见为结节型与肺炎型、间质型并存;胸膜渗出、胸膜块样增厚及心包渗出较少见。结论:恶性淋巴瘤在纵隔肺门淋巴结、肺、胸膜和心包等处有各种异常CT表现,CT检查可以准确显示肺部情况,且有利于疾病的诊断和鉴别诊断。
Objective: To investigate the chest CT findings of malignant lymphoma and to make timely diagnosis and differential diagnosis. Materials and Methods: Thirty-two cases of thoracic malignant lymphoma (classified as Hodgkin’s disease and non-Hodgkin’s lymphoma) were collected and pathologically confirmed. Results: Seven cases of Hodgkin’s disease and 25 cases of non-Hodgkin’s lymphoma were observed in this group of cases. The findings were as follows: (1) mediastinal, hilar lymph node enlargement, (2) pulmonary invasion, (3) pleural disease , (4) pericardial effusion or chest wall invasion. Mediastinal, hilar lymph nodes most common. There are four types of lung invasion: (1) mass (nodules) type; (2) miliary type, (3) pneumonia type; (4) interstitial. The most common nodular and pneumonia type, interstitial coexistence; pleural effusion, pleural thickening and pericardial exudation rare. CONCLUSION: Malignant lymphoma has abnormal CT findings in mediastinal hilar lymph nodes, lungs, pleura and pericardium. The CT examination can accurately show the condition of the lungs and is helpful for the diagnosis and differential diagnosis of the disease.
