摘要
目的回顾性分析原位腺癌(AIS)的临床及CT表现,提高AIS的诊断水平。方法收集2011年10月～2012年6月经手术病理诊断为AIS患者19例,按照2011版对AIS的定义评价病变性质,分析AIS在CT上的表现。CT评价指标包括:病灶大小、形态、边缘、密度、有无空泡征(或囊状影)、充气支气管征、胸膜凹陷、有无淋巴结肿大等。结果直径小于1.0cm共12例。91.67%呈磨玻璃密度影,分叶征及空泡征发生率分别为16.67%、0.08%,均未见明显毛刺征,充气支气管症及胸膜凹陷症。直径大于或等于1.0cm共7例。均呈磨玻璃密度影,其中3例表现为混合磨玻璃密度,4例表现为单纯磨玻璃密度,均出现分叶征、毛刺征,胸膜凹陷、空泡征及充气支气管征发生率分别为71.43%、57.14%、42.86%、14.29%,均无明显肺门及纵隔淋巴结肿大。结论 AIS影像表现复杂,应根据直径大小分别深入细致地分析,可提高本病的诊断。
Objective To develop the diagnostic level of adenocarcinoma in situ （AIS） by analyzing the clinical features and CT presentations BAC. Methods 19 patients with adenocarcinoma in situ by surgery were enrolled in our study from October 2011 to June 2012. The CT presentations of AIS were analyzed. Findings included the number （solitary or multiple）, size, morphous, contoum, density and gas-containing space of lesions were evauated. Other CT findings such as air bronchogram and lymphadenopathy were also assessed. Results In 12 cases with diameter less than 1.0 cm, 91. 67% presented with ground-glass opacity, lobulation and vacuole sign occurence rate was 16.67%, 0. 08% respectively and spiculation, air bronchogram and pleural indentation appeared in none of these AIS. In 7 patients with a diameter greater than or equal to 1.0 cm, the lesion showed a ground-glass opacity, one of 3 cases showed mixed ground glass density, 4 cases showed pure ground glass density, all showed lobulation, spiculation, pleural indentation, vacuole sign and air bronchogram occurence rate was 71.43%, 57.14%, 42.86 %, 14.29% respectively, had no hilar and mediastinal lymph node enlargement. Conclusion The imaging features of AIS are complicated, more exact diagnosis can be made after intensively investigating imaging features according to the diameter size.
