摘要
目的探讨细支气管腺瘤的CT影像表现,以提高对该病的诊断和认识。方法回顾性分析33例北京大学深圳医院2020年8月至2024年12月经手术病理证实的细支气管腺瘤的CT影像资料,分析总结其CT影像特征。结果33例细支气管腺瘤患者中,男13例,女20例,年龄30-72岁,平均53±13岁。位于右肺上叶6例,右肺中叶2例,右肺下叶13例,左肺上叶4例,左肺下叶8例。病灶表现为实性结节7例,纯磨玻璃结节13例,混合磨玻璃结节12例,磨玻璃影1例。其他征象有毛刺(5/33)、分叶(15/33)、空泡(18/33)、胸膜凹陷(10/33),所有病灶均未见钙化。33例病灶距胸膜的垂直距离范围为0-29mm,平均7.4mm±7.8mm。结论细支气管腺瘤的CT影像具有多样性,空泡征是最常见的征象,明确诊断需结合病理。
Objective To investigate the CT imaging manifestations of bronchiolar adenoma(BA)in order to improve its diagnostic accuracy and recognition.Methods A retrospective analysis was conducted on the CT imaging data of 33 patients with pathologically confirmed BA after surgical resection at Peking University Shenzhen Hospital from August 2020 to December 2024.The CT imaging features were analyzed.Results Among the 33 BA patients,13 were male and 20 were female,aged 30-72(53±13)years.Lesions were located in the right upper lobe(n=6),right middle lobe(n=2),right lower lobe(n=13),left upper lobe(n=4),and left lower lobe(n=8).Imaging presentations included solid nodules(n=7),pure ground-glass nodules(n=13),mixed ground-glass nodules(n=12),and ground-glass opacity(n=1).Additional findings included spiculation(5/33),lobulation(15/33),vacuole sign(18/33),and pleural indentation(10/33).None of the lesions showed calcification.The perpendicular distance from the lesion to the pleura ranged from 0 to 29 mm(average 7.4mm±7.8 mm).Conclusion The CT imaging features of BA are diverse,with vacuole sign being the most common finding.Accurate diagnosis requires a combination with pathology.
