摘 要:目的探讨微浸润型肺腺癌(MIA)在低剂量cT(LDCT)上的影像学表现。方法回顾性分析经LDCT筛查发现并诊断为微浸润肺腺癌患者34例临床资料,观察病灶的LDCT表现。结果34例患者中32例为单发磨玻璃结节,2例为多发磨玻璃结节(2个及以上),共36个结节;其中纯磨玻璃结节为11个(30.5%),混杂磨玻璃结节25个(69.5%)。病灶直径0.7~2.4cm,其中直径1.0-2.0cm共27个(75%),平均(1.7±0.3)cm。左肺上叶5个(13.8%),左肺下叶9个(25.0%),右肺上叶6个(16.6%)、右肺中叶8个(22.2%),右肺下叶8个(22.2%)。影像学征象包括空气-细支气管扩张征20个(55.6%),边缘清晰22个(61.1%),分叶征共29个(80.6%),其中深分叶9个(25.0%)、浅分叶20个(55.6%),毛刺征17例(47.2%),胸膜凹陷20例(55.6%)。支气管截断征6个(16.7%),血管集束征9个(25.0%)。结论在LDCT筛查中发现直径在1.0-2.0cm间的磨玻璃结节,特别是混杂磨玻璃结节,同时量化分型较高,病变边界清晰,或伴有分叶征、毛刺征、空气.细支气管扩张征及胸膜凹陷时,高度提示微浸润肺腺癌的诊断。Objective To research the performance of micro infiltration type lung adenocarcinoma (MIA) in the low - dose CT (LDCT). Methods The clinical data of 34 patients with lung adenocarcinoma who found by LDCT screening and diagnosed as micro infiltration were retrospectively analyzed, LDCT performance of lesions was observed. Results In 34 patients,32 cases of single grinding glass tubers,2 cases of multiple ground glass nodules (2 and above) ,a total of 36 nodules. With pure glass grinding nodule in 11 (30.5%) ,mixed grinding glass nodules 25 (69.5%). Lesions was 0.7 - 2.4cm in diameter, the diameter was about 1.0 - 2.0cm, a total of 27 (75.0%), an average of (1.7 ±0.3) cm. 5( 13.8% ) of left upper lobe,left lung lobe 9(25.0% ) ,6( 16.6% ) of the upper lobe, right lung middle in 8(22.2% ) ,characterized by lower lobe in 8(22.2% ). Radiographic signs included air -20 cases (55.6%), fine bronchiectasis sign clear edge in 22 ( 61.1% ), Ye Zheng a total of 29 (80.6%), including deep lobe 9 (25.0%), shallow lobes 20 (55.6%), burr 17 (47.2%), pleural indentation 20 (55.6%). Bronchus truncation 6 ( 16.7% ), vascular cluster 9 (25.0%). Conclusion Found in LDCT screening between 1.0 - 2.0cm in diameter of grinding glass nodules, especially the gnnding glass nodules, quantitative classification is higher at the same time, lesion boundaries clear, or points Ye Zheng, burr, air- with fine bronchiectasis and pleural indentation, micro infiltra- tion is characteristic and highly suggestive of lung adenocarcinoma.
