【摘要】：目的探讨微浸润性肺腺癌(MIA)的超高分辨率CT(UHRCT)表现及病理特征。方法经手术病理证实的微浸润性肺腺癌患者53例,共57枚结节,术前行UHRCT扫描,观察病灶的CT表现并与病理学对照分析。结果 49例为单发MIA结节,4例为两枚MIA结节;纯磨玻璃结节30枚,混合磨玻璃结节26枚,实性结节1枚;病灶直径(1.5±0.6)cm;类圆形/椭圆形51枚,不规则形结节6枚;瘤-肺界面征清楚52枚,分叶征19枚,空泡征10枚,细支气管充气征13枚,血管集束征24枚,胸膜凹陷征4枚;对MGGN量化分型,Ⅰ~Ⅱ型1枚,Ⅲ~V型25枚。结论 UHRCT表现为类圆形/椭圆形,PGGN或高量化MGGN,瘤-肺界限清楚,有细支气管充气征、空泡征及血管集束征,邻近胸膜轻度凹陷,无淋巴结、远处转移及胸膜侵犯,应高度怀疑MIA。
[Abstract]:Objective to investigate the histopathological features of micro invasive lung adenocarcinoma (mia) with ultra high resolution CT. Methods Fifty-seven microinvasive lung adenocarcinoma patients (57 nodules) confirmed by surgery and pathology were examined by UHRCT before operation. Ct findings of the lesions were observed and compared with pathology. Results 49 cases were single MIA nodules (n = 4, 2 MIA nodules), 30 pure ground glass nodules, 26 mixed ground glass nodules, 1 solid nodules, 1.5 卤0.6 cm diameter, 51 round / ellipsoid nodules and 6 irregular nodules. There were 52 clear interfacial signs, 19 lobular signs, 10 vacuole signs, 13 bronchiole inflatable signs, 24 vascular cluster signs, 4 pleural indentation signs, and 1 type 鈪，
