| 摘 要： | 目的:探讨肺黏膜相关淋巴组织(MALT)淋巴瘤的CT表现,以提高诊断水平。方法:回顾性分析7例经病理学证实的肺MALT淋巴瘤的CT及临床资料。结果:7例中多发病灶4例,单发病灶3例;肺炎实变型5例,结节肿块型2例。CT平扫5例肺炎实变型均表现为肺内条、片样肺实变,内见"支气管充气征",1例见多发边界较清楚的斑片磨玻璃密度结节影;2例结节肿块型表现为肺内单发密度较均匀、边界较清晰的肿块,最大直径分别约32 mm及38 mm,1例见"支气管充气征"。增强7例肿瘤均呈轻-中度均匀强化,5例见"血管漂浮征";1例纵隔多发淋巴结肿大,2例少量胸腔积液,2例胸膜局部增厚。结论:肺MALT淋巴瘤多数表现为肺内多发实变样病灶,少数表现为结节、肿块样病灶,同时伴有"支气管充气征"及"血管漂浮征",增强一般较均匀轻至中度强化,CT对其诊断具有重要的价值。

| Abstract: | Objective:To investigate the CT manifestation of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma and improve the diagnostic level. Methods:The CT and clinical data of 7 cases of pulmonary MALT lymphomas proved by pathology were reviewed retrospectively. Results:There were 4 cases of multiple lesions and 3 cases of solitary lesion among 7 cases, 5 cases were pneumonic consolidation type and 2 cases were nodular/mass type. On unenhanced CT, all 5 cases of pneumonic consolidation type showed strip or patch consolidations of lung, and "air bronchograms sign" can be observed. Multiple ground glass nodules with clear margin were observed in 1 case; two cases of nodular/mass type showed intrapulmonary solitary mass with homogeneous density and clear boundary, and the maximum diameter was 32mm and 38mm respectively. "Air bronchograms sign" can be observed in 1 case. On enhanced CT, all 7 cases showed mild to moderate homogenous enhancement, and "blood vessel floating sign" can be observed in 5 cases. Multiple mediastinal lymphadenopathy can be observed in 1 case, a small amount of pleural effusion was observed in 2 cases and partial pleural thickening occurred in 2 cases. Conclusions:Most pulmonary MALT lymphomas manifested as multiple consolidation lesions. A few manifested as pulmonary nodule or mass, accompanied with "air bronchograms", "blood vessel floating sign" and mild to moderate enhancement. CT has important value for its diagnosis. |
