多层螺旋CT对细支气管肺泡癌的诊断价值

The Diagnostic Value of Multislice Spiral CT of Bronchioloalveolar Carcinoma

目的探讨多层螺旋CT检查在细支气管肺泡癌的特征表现,为细支气管肺泡癌进行临床诊断和早期治疗提供依据。方法回顾性分析2009年3月至2012年1月入我院治疗的细支气管肺泡癌25例患者的临床资料,对其行多层螺旋CT检查并进行图像处理后对病灶的分布、部位、边缘特征及内部结构进行观察和分析。结果细支气管肺泡癌分炎症型、结节型和弥漫型。炎症型表现为双侧或单侧多个密度稍高、边缘不清晰、肺叶或肺段有实变;结节型病灶部位分布在胸膜下区和肺门区,病灶形态表现为中心低密度区、磨玻璃晕征、毛刺征尾征、血管集束等;弥漫型病灶呈双肺弥漫性分布,以肺中叶和下叶分布居多。病灶密度高,病灶边缘清晰或模糊,有部分细角状或棘状突起,部分结节病灶形状不规则或伴有尾征、晕征、部分融合成小片状、局限性小叶间隔增厚、条索网状改变、伴有小空洞征或空泡等。结论细支气管肺泡癌患者的多层螺旋CT表现具有一定的临床特征,在早期诊断治疗中,多层螺旋CT检查至关重要,是诊治该病必要的检查手段。

Objective To investigate the performance of multislice spiral CT examination in the characteristics of bronchioloalveolar carcinoma,bronchioloalveolar carcinoma,provide the basis for clinical diagnosis and early treatment.Method A retrospective analysis from March 2011 to January 2012 into the hospital treatment of 25 cases of bronchioloalveolar carcinoma in patients with clinical data row multislice CT and image processing,the distribution of lesions,location,edge features and internal structures were observed and analyzed.Result Bronchioloalveolar carcinoma sub-inflammatory,nodular and diffuse.Inflammatory manifestations of bilateral or unilateral density slightly higher,the edge is not clear,lobe or lung segment consolidation;nodular lesion sites located in the subpleural and hilar area,lesion morphology centered low-density areas ground-glass halo sign,spiculation tail sign,vessel convergence,etc.;diffuse lesions showed a diffuse distribution,the majority of lung middle lobe and lower lobe distribution.High density of lesions,lesion edge clear or fuzzy,there are some fine angular or spinous processes,part of the nodules with irregular shape or with the tail sign,halo sign,part of the integration into small pieces,and the limitations of interlobular septal thickening,as amended,The cable network change,with small cavities levy or vacuoles.Conclusion Bronchioloalveolar carcinoma in patients with multi-slice spiral CT findings with clinical features,early diagnosis and treatment,multislice CT is essential is the diagnosis and treatment of disease is necessary inspection tool.
