恶性淋巴瘤的肺部影像诊断

目的回顾性分析肺部淋巴瘤的影像表现,评价普通平片、CT在肺部淋巴瘤诊断中的作用,以便提高该病的诊断和治疗水平。方法收集经病理证实的35例恶性淋巴瘤(分为何杰金病和非何杰金病)患者的资料,对其平片、CT表现及组织病理学进行分析。结果淋巴瘤分为何杰金病和非何杰金病,本组病例何杰金病10例,非何杰金病25例。发现原发肺部淋巴瘤6例,肺部继发恶性淋巴瘤有29例。肺部继发恶性淋巴瘤肺部改变又可分为四类:①肿块(结节)型;②支气管血管淋巴型;③肺炎肺泡型;④粟粒型。结论恶性淋巴瘤在纵隔肺门淋巴结、胸膜和心包等处都有异常CT表现,CT检查可以发现肺部病变,且有利于反映肺部病变情况与范围。

IMAGE DIAGNOSIS OF PULMONARY MALIGNANT LYMPHOMA

Objective To evaluate the usefulness of radiography,CT in lung malignant lymphoma, to improve the accuracy of diagnosis and treatment of the disease. Methods To collect and analyze the imaging characteristics of radiography and CT of lung malignant lymphoma, all cases mentioned above were proved by histopathology. Results In the cases, 10 of 35 cases were Hodgkin’s disease(HD) ,The others were non-Hodgkin’s Lymphoma(NHL), primary lymphoma were 6 cases, secondary lymphoma were 29 cases. The imaging features of secondary lymphoma were different and complex, it could be classified into four different patterns bronchovascular-lymphangi-tis; ②nodular or mass; ③pneumonic-alveolar; and ④milliary-hematogenous. Conclusion Malignant lymphoma have abnormal signs in chest films and CT. We can find lung change by CT scan.CT scan is better than radiography and MRI.
