细支气管肺泡细胞癌的影像诊断(附27例报告)

Bronchioloalvcolar Carcinoma; Imaging Diagnosis (A report of 27 coses)

目的:探讨细支气管肺泡癌(BAC)的影像学诊断价值。材料和方法:27例经病理学证实的BAC(男9例、女18例,平均年龄59岁),每例胸X线平片检查、17例胸CT扫描、1例MRI检查、2例支气管动脉造影。结果:本组病例结节型13例(48.4％),弥漫型12例(44.4％),肺炎型2例(7.2％)。结节型瘤灶7mm～60mm,弥漫型以弥漫结节为主的多种征象混合存在,肺炎型则类似肺水肿或大叶性肺炎。 结论:X线检查和CT扫描是本病的主要影像学检查手段可为BAC提供充分的影像学诊断信息。

Purpose: To evaluate the imaging diagnosis valve for the bronchioloalveolar careinoma(BAC). Materials and methods: In this series 27 patients of BAC proved patholog-ically(male 9, female 18, average age 59 year) had the chest examinations from 1985 to 1997 included planfilm (n = 27),CT(n = 17)MRI(n=1),and bronchio-angiography(n= 2). Results: This series revealed gollowing three patterns:nodular (n= 13, 48. 4 % ) , diffu-sive(n=12, 44.4%) , and lobar consolidation(n = 2, 7.2%). Conclusions: the application of both of X-ray film and CT of chest can provided enough informations for the imaging diagnosis of BAC.
