【摘要】 目的分析单发肺炎实变型肺黏膜相关淋巴组织(MALT)淋巴瘤的多排螺旋CT(MSCT)表现,以提高其诊断及鉴别诊断水平。方法回顾性分析11例患者经手术病理证实的单发肺炎实变型肺MALT淋巴瘤的MSCT和临床资料。结果 11例患者中右肺中叶5例,下叶2例,左肺上叶1例,下叶3例;大叶性实变7例,节段性实变3例,非节段性实变1例;2例病灶边缘模糊,类似于炎症,6例边缘模糊程度介于炎症与肺癌之间,3例边缘相对清楚;同邻近胸大肌密度相比较,9例病灶呈略低密度,2例与胸大肌密度接近,CT值39.6~53.3 Hu,平均42.5 Hu;11例病灶内部均未见明显坏死、囊变,9例病灶内见形态及走行相对正常的"空气支气管征",其中3例内部同时伴有小囊腔;7例CT增强检查,均呈轻~中度较均匀强化,CT值50.5~85.7 Hu,平均66.1 Hu;5例病灶内见"血管漂浮征";11例病灶均未见明显胸腔积液,2例病灶邻近胸膜增厚,2例伴有纵隔内淋巴结肿大。结论单发肺炎实变型肺MALT淋巴瘤CT上往往表现为肿瘤样的实变、炎症样模糊边缘,多轻、中度较均匀强化,内部常有固有结构的残留,部分可见"空气支气管征"及"血管漂浮征"。MSCT对该肿瘤的的诊断及鉴别具有一定价值。更多还原

【Abstract】 Objective To analyze the MSCT findings of pulmonary mucosa-associated lymphoid tissue lymphoma as single lung consolidation,and improve the diagnostic level.Methods MSCT findings and clinical data of 11 cases of pulmonary mucosa-associated lymphoid tissue lymphoma as single lung consolidation proven by surgical pathology were reviewed retrospectively.Results Among 11 cases,7 cases located in right lung,4 cases located in left lung;10 cases showed the consolidation of diffetent degree;2 cases with dim edge like inflammation,6 cases showed dim edge in between inflammation and carcinoma,3 cases with clear edge.9 cases were equle to the density of the pectoralis major,2 cases were lower,with nearly 39.6 ~53.3 Hu,the mean value was 42.5 Hu.There were no obvious necrosis or cystic change in all lesion.Consolidation with air bron-chogram could be seen in 9 cases;7 cases showed homogen-eous enhancement of slightly to morderate degree in contrast enhancement CT,and the CT value were 50.5 ~ 85.7 Hu.the mean value was 66.1 Hu. "blood vessal floated-sign " can be seen in 5cases.There were no obvious hydrothorax in all lesions,2 cases showed pleural thickening,2 cases showed the intumescentia of lymph node in the mediastinum.Conclusion Pulmonary mucosa associated lymphoid tissue lymphoma as single lungconsolidation always shows the lung consolidation as tumours,dim edge as inflammation,homogeneous enhancement of slightly to morderate degree in contrast enhancement CT,consolidation with air bronchogram and "blood vessal floated-sign " can be seen in some lesions.更多还原
