淋巴瘤肺浸润的CT表现和病理对比

目的：探讨淋巴瘤肺浸润的特征性CT表现和病理学特征,以提高对本病的认识。方法：回顾性分析23例经病理证实的淋巴瘤肺浸润的CT影像资料,并与组织病理学和手术结果比较。结果：23例淋巴瘤中霍奇金淋巴瘤5例,非霍奇金淋巴瘤18例。单发病灶7例,多发病灶16例。肺叶肺段型9例,结节肿块型8例,混合型6例。CT病理对比研究显示支气管充气征（14/23,60.87%）、CT血管造影征（12/23,52.17%）、磨玻璃结节（3/23,13.04%）,跨叶病灶（4/23,17.39%）为较具特征性的征象,对诊断意义较大。结论：淋巴瘤肺浸润CT表现具有一定的特征性,对淋巴瘤肺浸润的诊断具有一定的临床价值。

Pulmonary involvement of lymphoma:CT features with pathologic correlation

Objective：To analyze the CT and pathology features of pulmonary involvement of lymphoma and to improve the understanding of this disease.Method：The CT findings of 23 cases with pulmonary involvement of lymphoma were retrospectvely analyzed and correlated with histopathology.Results：Of the 23 cases with pulmonary involvement of lymphoma,there were Hodgkin lymphoma （5 cases） and non-Hodgkin lymphoma （18 cases）.Multiple lesions were assessed in 16 cases and single lesion in 7 cases.The imaging findings were classified into 3 types：lobar and segmental involvement （9/23 cases,39.13%）,nodular or mass-like involvement （8/23 cases,34.78%） and mixed type （6/23cases,26.09%）.Air bronchogram （14/23 cases,60.8%）,CT angiogram sign （12/23 cases,52.17%）,ground glass opacity like nodules （3/23 cases,13.04%） and lesion across pulmonary lobes （4/23 cases,17.39%） were the characteristic features of pulmonary involvement of lymphoma.Conclusions：Relative characteristic CT features of pulmonary involvement of lymphoma could be revealed,which shows clinical significance in the diagnosis of the disease.
