28例细支气管肺泡癌的X线与病理分析

Radiological and pathological features of bronctllioloalveolar carcinoma (report of 28 cases)

目的 希望确定细支气管肺泡癌(Bronchioloalveolar Carcinoma,简称BAC,以下同)的组织学类型和其X线影像学之间的关系。方法 回顾性研究28例BAC患者的临床表现、X线改变及组织学特征;X线改变分为肿块结节型、炎症浸润型和弥漫型;组织学类型分为粘液型和非粘液型。结果 X线影像学上,肿块结节型22例,炎症浸润型4例,弥漫型2例;组织学类型上,粘液型13例,非粘液型15例;22例肿块结节型中非粘液型14例,占63.5％,6例浸润、弥漫型中粘液型5例,占83.3％。结论 组织学类型与X线影像学有一定的关系。

Objective To determine the correlation of radiological presentation of BAG with its histologic types. Methods Medical records of 29 patients were reviewed. The informations on clinical appearances, radiographic features and histological characteristics, were studied. The radiological presentation was classified into three types; tumorous nodule, inflammatory iafittrationi and diffusing lesion. All of the diagnosed BAC cases were reviewed and classified into two histologicaf types: mucinous and non-mucinous tumors. Results According to the radiologic presentation the nodular or tumorous type were identified in 22 patients, Inflammatory or infiltra-tive lesions found in 4 cases and diffusing lesion in 2 cases. According to the histological features concerned there were 13 of mucinous and 15 of non-mueinoms tumors. Fourteen of 22 patients with nodular or tumorous type were non-mucinous (63. 5%). There were 5 cases mith mucinous tumors in 6 cases of infiltrating and diffusing type (83. 3%). Conclusion There are certain association with radiological presentation of BAC and its histological types.
