摘　　要：目的探讨肺不典型腺瘤样增生(AAH)的64排容积CT表现及其鉴别诊断。方法回顾性分析经手术病理确诊的AAH 12例64排容积CT影像资料,与同期确诊的76例局限性磨玻璃密度结节(GGO)患者的CT资料对比,对病灶的部位、大小、形态、边缘征象、内部结构和邻近结构关系进行评价。结果 AAH以纯GGO多见,GGO良性组纯磨玻璃密度结节和混合密度结节均可见,GGO恶性组以混合密度结节为主,分叶征、毛刺征、胸膜凹陷征及血管集束征AAH与良、恶性GGO间比较差异均有统计学意义(P<0.05),空泡征、细支气管充气征AAH与良、恶性GGO间比较差异均无统计学意义(P>0.05)。结论 AAH以纯GGO为主,直径多<10 mm,无毛刺征、胸膜凹陷征及血管集束征,分析GGO内部实性成分有助于良、恶性的鉴别诊断,但最终确诊仍需组织病理学。Objective To investigate the 64-slice volume CT findings and differential diagnosis of the pulmo-nary atypical adenomatous hyperplasia （ AAH） .Methods The data of 64-slice volume CT image of 12 cases of patho-logically confirmed pulmonary AAH was made retrospectively .The CT data were compared with those of the 76 cases of localized ground-glass opacity（GGO） in terms of the lesion location ,size,shape,edge signs,internal structure and relationship to adjacent structures .Results Pure ground-glass density nodules were commonly seen in AAH group , pure ground-glass density and mixed-density nodules were seen in benign group , and mixed-density nodules account for the majority in malignant group .There were statistical differences between AAH group and benign or mglignant GGO group in the aspects of lobulation sign,spicular sign,pleural indentation sign and vascular convergence sign （P〈0.05 ） .However ,there showed no significant differences in the signs of vacuole sing and air branchogram between the AAH group and benign GGO group or malignant GGO group （ P〉0.05 ） .Conclusion Pure ground-glass density nodules are the main constituent seen in AAH group .The nodules′diameter were commonly less than 10mm.And no lobulation sign,spicular sign,pleural indentation sign or vascular convergence sign can be seen in the AAH group .It can do help in differential diagnosis analyzing the CT value of the solid component .However,only the histopathology result is the real and the last diagnosis .
