摘　　要：目的:探讨肺炎型浸润性黏液腺癌(Pneumonic-type pulmonary invasive mucinous adenocarcinoma,PPIMA)的^(18)FFDG PET/CT的影像表现特征。方法:回顾性分析20例经手术及穿刺活检病理证实的PPIMA患者影像资料,所有患者均行^(18)FFDG PET/CT显像,观察病灶形态、密度、病灶周围及内部征象、代谢及远处转移情况。结果:20例PPIMA中,2例(10.0%)单发片状实变影、18例(90.0%)实变影伴磨玻璃影、结节影多种形态混合存在、多灶性分布。16例(80.0%)见“异常充气支气管征”;12例(60%)见空洞及空腔;8例(40%)伴灶周磨玻璃密度灶;11例(55.0%)邻近叶间裂膨隆;4例(20%)出现肺内转移。实变病灶内部密度不均匀,CT值(27.2±6.8)HU;代谢高低不一,SUVmax 5.2±1.9;实变病灶SUVmax与CT值间均具有明显相关性(r=0.765,P=0.000)。结论:PPIMA的^(18)F-FDG PET/CT有一定的特征表现,有助于本病的早期诊断及分期。Objective:To investigate^(18)F-FDG PET/CT imaging features of pneumonic-type pulmonary invasive mucinous adenocarcinoma(PPIMA).Methods:The imaging data of 20 patients with PPIMA confirmed by surgery and biopsy were retrospectively analyzed.All patients underwent^(18)F-FDG PET/CT imaging to observe the lesion morphology,density,signs around and inside the lesion,metabolism and distant metastasis.Results:Among the 20 cases of PPIMA,2 cases(10.0%)had single flaky solid shadow,and 18 cases(90.0%)had multiform and multifocal distribution of solid shadow with ground glass shadow and nodule shadow.Abnormal air bronchial sign was found in 16 cases(80.0%).Cavity and cavum were found in 12 cases(60%).There were 8 cases(40%)with peri-focal ground glass density.The adjacent interlobar fissure was enlarged in 11 cases(55.0%).Intrapulmonary metastasis occurred in 4 cases(20%).The internal density of the solid lesions was not uniform,and CT value was(27.2±6.8)HU.Metabolism varied,SUVmax 5.2±1.9.There was a significant correlation between SUVmax and CT values(r=0.765,P=0.000).Conclusion:^(18)F-FDG PET/CT of PPIMA has certain characteristics,which is helpful for early diagnosis and staging of PPIMA.
