摘要

目的：探讨细支气管肺泡癌的高分辨CT（HRCT）征象。方法：回顾分析经病理证实的41例细支气管肺泡癌的HRCT表现，分析有助诊断的HRCT征象及病理基础。结果：孤立结节型18例，其中15例位于肺外周或胸膜下，磨玻璃密度影10例，形态不规则或斑片状影8例，空泡征和/或空气支气管征14例，胸膜凹陷征12例；弥漫型14例，其中均匀实变7例，蜂房征4例，磨玻璃密度8例,支气管气像6例,腺泡样结节6例。结论：HRCT是细支气管肺泡癌的诊断及鉴别诊断的重要手段之一。

Abstract

Objective: To study the appearance of bronchioloalveolar carcinoma(BAC) on high-resolution CT. Methods: HRCT scans of 41 patients with pathologically proven BAC were retrospectively analyzed. 7 HRCT findings were separately recorded into 3 types(solitary nodule, multi-nodular, diffusion type) and were assessed with pathologic correlation. Result: HRCT findings of solitary nodule(n=18) are: typical peripheral or subpleural location in 15; pulmonary lesion with irregular margin forming a stellate or patchy pattern 8; vacuole sign and/or brochiologram 14; pleural retraction 12; The features of single lesion in multi-nodular(n=9) were the same as the former; Diffuse consolidative type(n=14): lobar or segmental homogenous consolidation (n=7); “withered tree” sign(n=4); “honey comb” sign(n=6); ground-glass opacity(n=8); acinar nodules(n=6). Conclusion: HRCT is an important method to determine the diagnosis and differential diagnosis of BAC.
