摘　　要：目的探讨原发性肺淋巴瘤(PPL)的^(18)F氟代脱氧葡萄糖正电子发射断层显像/计算机体层成像(^(18)F-FDG PET/CT)表现。方法回顾性分析11例经病理证实为PPL患者的^(18)F-FDG PET/CT影像学表现,并测量病灶的最大标准化摄取值(SUVmax)。结果11例患者中,黏膜相关淋巴组织结外边缘区B细胞性淋巴瘤(MALT)4例,弥漫性大B细胞淋巴瘤(DLBCL)5例,外周T细胞淋巴瘤(PTCL)1例,结外NK/T细胞淋巴瘤(ENKTCL)1例。病变累及右肺5例,左肺4例,同时累及双肺2例。单发结节(肿块)型4例,多发结节(肿块)型2例,肺实变型4例,混合型1例。^(18)F-FDG PET/CT显示全部病灶均表现为放射性浓聚影,SUVmax 1.0~18.7。结论^(18)F-FDG PET/CT可以准确显示PPL病灶的形态、分布及肿瘤的代谢情况,当SUVmax值升高,且同时出现空气支气管征、血管造影征、晕征及跨叶分布征可考虑诊断为PPL。Objective To investigate the^(18)F fluorodeoxyglucose positron emission tomography/computed tomography(^(18)F-FDG PET/CT)manifestations of primary pulmonary lymphoma(PPL).Methods The^(18)F-FDG PET/CT imaging findings of 11 patients with pathologically confirmed PPL were analyzed retrospectively,and the maximum standardized uptake value(SUVmax)of the lesions was measured.Results Among the 11 patients,there were 4 cases of mucosa-associated lymphoid tissue lymphoma(MALT),5 cases of diffuse large B-cell lymphoma(DLBCL),1 case of peripheral T-cell lymphoma(PTCL),and 1 case of extranodal NK/T-cell lymphoma(ENKTCL).The lesions involved right lung in 5 cases,left lung in 4 cases,and both lungs in 2 cases.There were 4 cases of solitary nodular type,2 cases of multiple nodular type,4 cases of consolidation type,and 1 case of mixed type.^(18)F-FDG PET/CT showed that all 11 lesions appeared as hypermetabolic foci with SUVmax ranging from 1.0 to 18.7.Conclusion The^(18)F-FDG PET/CT can accurately show the morphology,distribution and metabolism of PPL,and when air-bronchogram sign,vascular enhancement sign,halo sign,and cross-lobe distribution sign occur simultaneously along with an increase in SUVmax,PPL should be considered as a possible diagnosis.
