摘　　要：目的分析肺黏膜相关淋巴组织(mucosa-associated lymphoid tissue,MALT)淋巴瘤多层螺旋电脑断层扫瞄(multilayer spiral computed tomography,MSCT)影像表现及特征,提高对该病的认识及诊断准确性。方法回顾性分析16例经病理证实肺MALT淋巴瘤患者的MSCT表现。结果 16例肺MALT淋巴瘤患者中单发6例,多发10例。根据MSCT病变形态分布,将16例MALT病变分为三类:结节/肿块型(7例),渗出/实变型(6例),混合型(3例)。病变周围血管支气管束增粗14例,8例病灶可见钙化。空气支气管征11例,其中9例支气管扩张。4例结节/肿块型呈"钻缝"样生长。16例中有13例行增强扫描,其中11例均匀强化,11例可见血管造影征。3例纵隔淋巴结增大,8例合并胸水。结论肺MALT淋巴瘤MSCT影像学表现具有一定特征性,结合临床惰性生长表现,可提示肺MALT淋巴瘤的诊断。Objective To analyze the characteristics of multilayer spiral CT(MSCT)images of pulmonary mucosa-associated lymphoid tissue(MALT)lymphoma for improving the diagnostic accuracy.Methods The MSCT findings of 16 patients with lung MALT lymphoma pathologically confirmed were analyzed retrospectively.Results Among the 16 patients,6 patients suffered from single lung MALT lymphoma and 10 from multiple ones.According to the MSCT morphology,MALT lymphomas were divided into three types:nodular/mass pattern in 7 cases,exudate/consolidation pattern in 6 cases and mixed pattern in 3 cases.Fourteen cases showed thickened vascular bronchial bundle around the lesions,and 8 cases showed calcification within the lesions.And 11 cases had air bronchial sign,including 9 cases of bronchiectasis.Four cases of nodular/mass pattern showed drilled-like growth.Among the 16 patients,13 patients received enhanced scanning,including 11 patients receiving uniform enhancement,and as a result,11 patients showed angiogram sign.Three cases had enlarged mediastinal lymph nodes and 8 cases had pleural effusion.Conclusion The MSCT of lung MALT lymphoma has certain characteristics,therefore,the lung MALT lymphoma can be diagnosed combined with the clinical manifestation of inert growth.
