肺黏膜相关淋巴组织淋巴瘤的CT表现

CT findings of pulmonary mucosa-associated lymphoid tissue lymphoma

目的:分析肺黏膜相关淋巴组织(mucosa-associated lymphoid tissue,MALT)淋巴瘤的CT表现,提高对肺MALT淋巴瘤的认识。方法:分析经肺穿刺活组织病理学检查证实的12例肺MALT淋巴瘤患者的临床和影像学资料,患者均接受胸部CT平扫。结果:12例患者CT扫描均见肺实变,其中5例为单发,7例为多发。12例患者中11例实变肺组织内见扩张支气管影及多发空泡影,9例伴肺内随机分布的多发结节及肿块影,2例伴多发空腔,1例伴胸膜下多发磨玻璃影。结论:肺实变是肺MALT淋巴瘤常见的CT表现,以扩张的空气支气管并多发空泡影为特征,肺结节及肿块、空腔、磨玻璃影均是肺MALT淋巴瘤特征之一。

Objective:To investigate the CT manifestations of pulmonary mucosa-associated lymphoid tissue(MALT)lymphoma and improve the understanding of this disease.Methods:The clinical and imaging data of 12 cases of lung MALT lymphoma confirmed by transcutaneous lung biopsy and pathology were analyzed.All patients underwent plain CT scan of the chest.Results:A total of 12 cases of CT were manifested as pulmonary consolidation,of which 5 cases were solitary lesion and 7 cases were multiple lesion.The sign of dilated air bronchograms and multiple empty bubbles were seen in 11 of 12 cases with pulmonary consolidation lesions,randomly distributed multiple nodules and masses in 9 cases,multiple cavities in 2 cases,and under subpleural abrasion with multiple ground-glass opacity in 1 case.Conclusion:Pulmonary consolidation was a common CT manifestation of pulmonary MALT lymphoma.It is characterized by air bronchogram sign and multiple empty bubbles with bronchiectasis.Pulmonary nodules and masses,cavities,and ground glass opacity were also one of the features of the disease.
