摘要
目的探讨肺黏膜相关淋巴组织型(MALT)淋巴瘤的CT表现,提高对该病的认识及诊断水平。方法回顾性分析13例经手术及病理证实的肺MALT淋巴瘤CT表现。结果 (1)单发病灶4例,多发病灶9例,其中多发实变5例,多发肿块结节合并间质性改变3例,多发磨玻璃影1例;(2)实变影11个病灶,均见扩张"空气支气管征",3例跨叶分布;结节共41枚,其中分叶34枚,边缘模糊31枚,胸膜下分布27枚,沿支气管血管束分布11枚,"细支气管征"或"空泡征"28枚;肿块9枚,均为分叶状,边缘模糊7枚,"空气支气管征"7枚。结论肺MALT淋巴瘤常表现为两肺多发实变、结节和肿块,扩张"空气支气管征"对诊断有提示意义;多发分叶状肿块和跨叶分布的实变,多发的胸膜下或沿支气管血管束分布的伴"细支气管征"或"空泡征"的分叶状结节,应考虑MALT淋巴瘤的可能。
Objective To analyze the CT appearances of pulmonary mucosa associated lymphoid tissue type （ MALT ） lymphoma. Methods The CT appearances of 13 cases with pathologically proved pulmonary MALT lymphoma were retrospectively analyzed. Results （ 1 ） There were 4 cases with single lesion and 9 cases with multiple lesions. Lesions presented as multiple consolidations in 5 cases, as masses with multiple nodules and interstitial change in 3 cases and as multiple ground-glass opacity （ GGO ） in 1 case. （ 2 ） Total 11 lesions were consolidation, all appeared as air bron- chogram, and 3 of them were crossed leaves distribution. 41 nodules were identified totally. 34 of them were shallow lobu- lated, 31 had indistinct border,27 were subpleural and 11 were bronchial vessels scabbard distribution. Air bronchogram was found in 28 cases. Total 9 masses were identified, all shallow lobulated, indistinct border in 7 lesions, and air bron- chogram in 7 lesions. Conclusion Imaging characteristics of pulmonary MALT lymphoma are usually multiple consolida-tions, nodules, or masses, part of which with indistinct border and air bronchogram have tip significance to diagnose. Multi-ple lobulated mass, consolidation crossed leaves, multiple lobulated nodules with vacuole sign distributed subpleural and bronchial vessels scabbard may be MALT lvmohoma.
