目的 提高对原发性肺非霍奇金淋巴瘤CT表现的认识.方法 回顾性分析经病理及临床随访证实的19例原发性肺非霍奇金淋巴瘤的CT表现.结果 CT表现为结节影7例,肿块影8例,大多边界模糊,强化明显,病变内常可见支气管充气征;斑片影9例,常为双肺多发,呈散在分布;实变影7例,多为大叶性实变,强化明显,病变内常可见支气管充气征;间质性改变1例,表现为双肺弥漫性磨玻璃影、网格影;混合影10例,为多种影像表现并存;胸腔积液4例,较为少见.结论 原发性肺非霍奇金淋巴瘤CT表现形式多样,具有一定特征性,CT检查结合临床表现有助于该疾病的诊断.

CT findings of primary pulmonary non-Hodgkin lymphoma

Objective To analyze the CT appearances of primary pulmonary non-Hodgkin lymphoma(PPNHL)in order to improve its diagnosis.Methods CT manifestations of 19 cases with PPNHL confirmed by pathology and clinical follow-up were retrospectively analyzed.Resuits Nodules 7 cases and masses 8 cases in PPNHL were ill-defined and markedly enhanced,in which air bronchogram was commonly seen.Muhiple patchy areas distributed in the bilateral lungs were found in 9 cases.Consolidation 7 cases was lobar and markedly enhanced,in which air bronchogram was commonly seen.Interstitial change manifested as bilateral diffuse ground-glass opacities and reticular shadow was found in 1 case.Mixed imaging manifestations were detected in 10 cases.Pleural effusion 4 cases was uncommon.Conclusion CT manifestations of PPNHL are varied,but some specific imaging features still exist,CT examination combined with clinical manifestations is helpful for the diagnosis of PPNHL.
