    摘要:

    目的:探讨肺黏膜相关性淋巴瘤(MALT淋巴瘤)的18F-脱氧葡萄糖(18F-FDG) PET/CT显像特点及其诊断价值-方法:回顾性分析3例经病理证实的肺MALT淋巴瘤的临床资料和PET/CT影像特点-结果:胸部CT表现为单发或多发实变影-肿块影-磨玻璃样影,内可有达肺外带的支气管充气征;少数可合并胸腔积液-胸膜不规则结节样增厚,可伴有淋巴结增大-3例病灶18F-FDG代谢增高-结论:肺MALT淋巴瘤是非霍奇金淋巴瘤一独特亚型,影像学表现为边缘模糊的肿块或实变影,内可有达肺外带的支气管充气征,FDG PET代谢增高,确诊主要依靠病理组织学和免疫组化-

    Abstract:

    Objective:To investigate the 18F-FDG PET/CT manifestations and diagnostic value in patients with pulmonary mucosa associated lymphoid tissue lymphoma. Methods:Clinical records and characteristic18F-FDG PET/CT findings in 3 patients with pulmonary mucosa associated lymphoid tissue lymphoma confirmed by pathology,were retrospectively analyzed. Results:The main chest CT manifestations of pulmonary mucosa associated lymphoid tissue lymphoma were single or multiple mass with blurred contours,consolidation with air bronchogram and localized alveolar opacity. Pleural tuberous thickening,pleural effusion and lymph node swelling were also seen. Three patients had high FDG uptake lesions. Conclusion:Pulmonary mucosa associated lymphoid tissue lymphoma is an unusual subtype of non-Hodgkin lymphoma. Imaging manifestations are mass with blurred contours or consolidation with air bronchogram and high FDG uptake. The final diagnosis should be made by histology and immunohistochemistry.
