肺黏膜相关淋巴组织淋巴瘤的CT平扫、增强及HRCT表现

Imaging findings of non-contrast CT scan, enhancement and HRCT of pulmonary mucosa-associated lymphoid tissue lymphoma

摘要:

目的 探讨肺黏膜相关淋巴组织(MALT)淋巴瘤的CT平扫、增强及HRCT表现,提高对本病的认识.方法 收集河南科技大学第一附属医院自2002年5月至2011年10月16例肺MALT淋巴瘤患者资料,均经病理证实,所有病例行CT平扫,7例加增强、9例加高分辨率CT (HRCT)扫描.对16例CT资料进行回顾性分析.结果 本组病例的主要CT征象为实变、结节及肿块,其中11例出现2种或以上,5例仅出现1种;同时伴随正常或扩张支气管气像13例,磨玻璃影(GGO)10例,间质性改变及囊腔各5例,部分肺不张及纵隔肺门淋巴结肿大各4例,胸腔积液2例,气管支气管MALT淋巴瘤1例.病变分布特征:12例多发,4例单发;实变、大结节及肿块多沿血管支气管束分布,微小结节呈淋巴管周围性分布,其中8例伴随其他征象出现.增强后气管大结节轻度强化;实变及肿块以明显强化多见,大结节以轻度强化多见,3例可见血管造影征.结论 大多数肺MALT淋巴瘤表现为含正常或扩张支气管气像沿血管支气管束分布的实变、大结节及肿块,同时伴随GGO及淋巴管周围性分布的微小结节,特征性的增强表现为明显强化伴血管造影征;少数合并肺间质性改变、囊腔、部分肺不张、纵隔肺门淋巴结肿大、胸腔积液及气管支气管树MALT淋巴瘤.

Objective To explore the imaging findings of non-contrast CT scan,enhancement and HRCT of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma.Methods All the patients with pathologically proven pulmonary MALT lymphoma underwent non-contrast CT scan,of which 7 underwent CT enhancement and 9 had HRCT.CT features of 16 patients were retrospectively reviewed.Results Major CT signs of 16 cases were consolidations,nodules and masses,of which 11 had two or more signs and 5 had only one.Together with them,normal or dilated air bronchograms were seen in 13 cases,ground-glass opacity (GGO) in 10,interstitial changes and cysts in respective 5,partial atelectasis and mediastinal and hilar lymphoadenopathy in respective 4,pleural effusion in 2 and MALT lymphoma of tracheobronchial tree in 1.Multiple lesions were found in 12 cases and solitary lesion in 4 cases.Consolidations,greater tubercles and masses mostly had a peribronchovascular distribution.Micronodules occurred in a perilymphatic distribution,of which 8 accompanied other signs.On CT enhancement scans,greater tubercles in the trachea had mild enhancement; most of the consolidations and masses had obvious enhancement,while greater tubercles mostly mild enhancement.CT angiogram sign was found in 3 cases.Conclusion Most cases with pulmonary MALT lymphoma have consolidations,greater tubercles and masses with normal or dilated air bronchograms which have a peribronchovascular distribution,together with GGO and micronodules in a perilymphatic distribution; the distinctive manifestations are obvious enhancement with CT angiogram sign.Minority cases have interstitial changes,cysts,partial atelectasis,mediastinal and hilar lymphoadenopathy,pleural effusion and MALT lymphoma of tracheobronchial tree.
