摘要
目的探讨肺黏膜相关淋巴组织型(MALT)淋巴瘤cT或18F-脱氧葡萄糖(FDG)PET—cT表现及其诊断价值。方法回顾性分析14例经手术及病理证实的肺MALT淋巴瘤的cT或18F—FDGPET—CT表现特点。结果单肺病灶7例,双肺病灶7例,其中单发实变影3例,单发肿块影3例,单发结节影1例,多发结节影1例,肿块影合并结节影、斑片状影1例,实变影合并斑片状影4例,弥漫性问质性病变1例。9例有支气管充气征,5例有cT血管造影征。2例FDG代谢不均匀增高,最大标准摄取值超过2.5。结论肺MALT淋巴瘤的影像特征性表现主要为单发或多发结节、肿块或实变影,内有支气管充气征,18F—FDG高代谢,确诊主要依靠病理组织学和免疫组织化学。
Objective To assess the value of CT or PET-CT with fiuorine-18-1abeled fiuorodeoxyglucose (FDG) for the diagnosis of pulmonary mucosa-associated lymphoid tissue (MALT) type lymphoma. Methods The CT or FDG PET-CT findings in 14 patients with pathologically proved pulmonary MALT lymphoma were retrospectively analyzed. Results Lung lesions were unilateral in 7 patients and bilateral in 7 patients. Lesions presented as a single mass in 3 patients, as a single consolidation in 3 patients, as a nodule in 1 patient, as multiple nodules in 1 patient, as multiple patchy consolidations in 4 patients, as a mass with multiple nodules and patchy consolidations in 1 patients, as diffuse interstitial change in 1 patients. Air bronehogram was found in 9 patients and CT angiogram sign in 5 patients. On PET- CT, lesions showed heterogeneous FDG uptake in 2 patients, maximum standard uptake value was higher than 2. 5. Conclusion Imaging characteristics of pulmonary MALT lymphoma are single or multiple nodules or consolidations with air bronchogram on CT, and heterogeneous high FDG uptake on PET-CT.
