摘　　要：目的 研究肺黏膜相关淋巴组织（MALT）淋巴瘤的CT表现,提高对该病的认识及鉴别诊断能力.方法 回顾性分析经病理证实的12例MALT淋巴瘤的CT表现,影像观察指标为病灶的数量、分布、形态、密度及伴随征象.结果 12例MALT淋巴瘤中共检出肺实变、肺肿块、肺结节、磨玻璃样病灶32个,病灶单发2例,多发10例;多发病例中单肺多发2例,双肺多发8例.肺实变10例共21个病灶,其内均可见支气管充气征,1例2个病灶内见支气管扩张;肺肿块或结节影3例共5个病灶,3个病灶内可见支气管充气征;磨玻璃样改变2例共6个病灶;1例伴纵隔及肺门淋巴结肿大.结论 MALT淋巴瘤CT上常表现为双肺多发、含有支气管充气征的肺实变、肿块、结节样或磨玻璃样改变;上述影像表现及相对缓慢的病变过程提示MALT淋巴瘤的诊断.Objective To study the CT findings of pulmonary mucosa-associated lymphoid tissue （MALT） lymphoma. Methods The CT examinations of 12 patients with pathologically proven pulmonary MALT lymphoma were reviewed retrospectively. Evaluated imaging findings included number, distribution,shape, attenuation and other associated findings of each lesion were evaluated. Results Thirty-two pulmonary lesions, including consolidations, masses, nodules and lesions with ground glass attenuation,were identified in 12 patients. Multiple lesions were founded in 10 of 12 patients and solitary lesion in 2 patients. Multiple lesions found in one lung in 2 patients, and multiple lesions found in both lungs in 8 patients. Ten cases demonstrated 21 consolidation lesions with air bronchogram, and one of the ten cases demonstrated two lesions with airway dilatation. Three cases demonstrated 5 masses or nodular lesions, 3 of these 5 lesions showed air bronchogram. Two cases demonstrated 6 ground glass attenuation lesions. One case showed mediastinal and hilar lymphadenopathy. Conclusion Pulmonary MALT lymphoma usually appears as multiple bilateral consolidations, masses, nodules with air bronchogram or lesions with groundglass attenuation at CT imaging. The imaging findings described above and with an indolent clinical course may suggest the diagnosis of pulmonary MALT lymphoma.
