摘要
目的:探讨弥漫型细支气管肺泡癌的CT诊断要点,以减少误诊。材料和方法:回顾性分析23例病理证实的弥漫型细支气管肺泡癌的CT影像,其中13例首次CT误诊,分别为炎症7例、结核3例、转移瘤3例。结果:CT表现可分为多发结节型5例、肿块型2例及肺炎样型16例。其中仅2例典型叶段分布者,3例叶段实变为主及4例蜂房样者提出了弥漫型肺泡癌的诊断,弥漫结节型、肿块型及散在斑片影均未能有效提示诊断。结论:弥漫型肺泡癌表现类型多样,典型叶段分布的多发结节、有血管造影征和支气管充气征的单/多叶段实变、蜂房状浅淡密度等较有特征性,可提示诊断。
Purpose: To study the CT diagnostic characteristics of diffuse bronchioloalveolar carcinoma(DBAC) . Materials and Methods: The CT features of pathologically verified DBAC in 23 patients were retrospectively analyzed. Thirteen of them were misdiagnosed pneumonitis, tuberulosis and metastasis when first - time examined.Results: The manifestation of DBAC were classified into three types: multi -nodular(5), massive(2) and pneumonia - like( 16) . Two cases with typical lobar distribution, 3 with lobar consolidation and 4 with honeycombing suggested DBAC. Diffuse nodule, mass and patchy opacity did not suggest DBAC. Conclusion: The DBAC had kinds of manifestation. Multinodule with typical lobar distribution, lobar consolidation with angiogram and bronchiologram, and honeycombing opacity were characteristic to suggest DBAC.
