【摘要】 目的探讨多层螺旋CT(MSCT)在肺黏膜相关淋巴组织(MALT)淋巴瘤诊断中的应用价值。方法回顾性分析我院自2007年6月~2014年11月经手术或穿刺病理证实为肺黏膜相关淋巴组织淋巴瘤的9例患者MS(T资料。所有患者均行CT平扫及增强扫描,CT表现由两名影像科医师共同分析。结果 9例患者中,病变为单发4例,多发为5例。共检出肺实变、结节、磨玻璃影及肿块病灶24个,其中肺实变伴支气管充气征为最常见表现,共计14例。肺结节、磨玻璃影及肿块病灶分别为3个、5个及2个。6例可见"血管漂浮征"。增强扫描呈轻至中度均匀强化,所有患者未见胸腔积液,纵膈及双侧肺门未见肿大淋巴结。结论肺MALT淋巴瘤在CT上多表现为单发或多发实变影伴支气管充气征,亦可见表现为结节、磨玻璃影或肿块,对于以上影像表现并且临床病程发展缓慢,抗炎效果不佳,应该考虑肺MALT淋巴瘤的诊断,MSCT在肺MALT淋巴瘤的临床诊治中具有重要价值。更多还原

【Abstract】 Objective To discuss the diagnosis value of MSCT in pulmonary mucosa-associated lymphoid tissue(MALT)lymphoma.Methods MSCT data of 9 patients in our hospital from July 2007 to November 2014 were retrospectively analyzed.All cases were diagnosed as pulmonary MALT lymphoma with pathological examination by surgery or biopsy.CT contrast examination was performed.Results In 9 cases,single lesion was found in 4 patients and multiple lesions in 5 patients.There were 24 lesions,including consolidations,nodules,glass attenuation lesions and masses.14 consolidations with air bronchogram were demonstrated.Nodules,glass attenuation lesions and masses were 3,5 and 2 respectively. "Blood vessel floated-sign" can be seen in 6 patients.All cases showed homogeneous enhancement of slightly to moderate degree in contrast enhancement CT.There were no hydrothorax and intumescentia of lymph node in hilus pulmonis or mediastinum.Conclusion MSCT characteristics of pulmonary MALT lymphoma are single or multiple consolidations with air bronchogram,or nodules,glass attenuation lesions and masses.Pumonary MALT lymphoma should be considered in patients with such CT performance with indolent clinical course and not good anti-inflammatory effect.MSCT examination is of importance in diagnosis and treatment of pulmonary MALT lymphoma.更多还原
