以肺实变表现为主的淋巴瘤与肺癌的CT征象分析

Lung cancer versus pulmonary lymphoma characterized by pulmonary consolidation:CT imaging features analysis

目的探讨以肺实变为主的肺淋巴瘤和肺炎型肺癌(pneumonic-type lung cancer,PTLC)患者的CT征象特点。方法搜集在我院CT/超声引导下经皮肺穿刺活检证实、胸腔镜辅助下手术切除病理证实或纤维支气管镜活检证实且CT表现以实变为主的32例肺淋巴瘤(2008年5月-2016年9月)和32例肺癌(2014年10月-2016年9月)病例,回顾性分析两组的一般临床资料及CT征象。结果肺淋巴瘤组年龄较肺癌组轻(P<0.05);肺淋巴瘤组双肺实变影、双肺多发结节及间质性改变、纵隔淋巴结增大均多于肺癌组(P<0.05)。结论患者年龄、病变位置、病变外周的伴随征象、纵隔淋巴结改变有助于鉴别以肺实变表现为主的淋巴瘤与肺癌。

Objective To compare the CT imaging features between pulmonary lymphoma and pneumonic-type lung cancer characterized by pulmonary consolidation.Methods CT findings mainly characterized by pulmonary consolidation in 32 cases with pulmonary lymphoma（from May 2008 to September 2016） and 32 cases with lung cancer（from October 2014 to September 2016） who diagnosed by CT/ultrasound guided percutaneous lung biopsy or video-assisted thoracoscopic surgery（VATS） or transbronchial lung biopsy（TBLB） were included in this study.All clinical data and CT imaging findings were collected and analyzed retrospectively.Results Patients in pulmonary lymphoma group were younger than those in lung cancer group（P〈0.05）.Proportions of Bilateral lung consolidation, multiple pulmonary nodules and interstitial changes, mediastinal lymph node enlargement in pulmonary lymphoma group were higher than those in lung cancer group（P〈0.05, respectively）.Conclusion Patient＇s age, lesion location, associated changes, mediastinal lymph nodes enlargement are indicative to differentiate pulmonary lymphoma from lung cancer characterized by pulmonary consolidation.
