We reviewed CT scans in 38 cases with pathologically proved bronchioloalveolar carcinoma. CT revealed three CT patterns: solitary, pneumonic and diffuse forms. The solitary pattern (22 patients) had a high percentage of air bronchograms (95%), pleural indentation (77%) and spiculation (68%). The pneumonia-like pattern (16 lesions in 10 patients) had air bronchograms in all cases (100%), low attenuation (88%) and protrusion of interlobar fissures (63%). The diffuse form (six patients) had 2 or 3 mm diffuse small nodules scattered throughout the entire lung. CT of bronchioloalveolar carcinoma revealed many findings and was useful in recognizing the tumor distribution and extent. We conclude that CT is helpful for the diagnosis and evaluation of bronchioloalveolar carcinoma.
我们回顾了38例经病理证实的细支气管肺泡癌患者的CT扫描结果。CT显示出三种CT表现形式：孤立型、肺炎型和弥漫型。孤立型（22例患者）中，空气支气管征出现的比例较高（95%），胸膜凹陷征（77%）和毛刺征（68%）。肺炎样型（10例患者中的16个病灶）在所有病例中均有空气支气管征（100%）、低密度影（88%）和叶间裂突出（63%）。弥漫型（6例患者）有2或3毫米的弥漫性小结节散布于全肺。细支气管肺泡癌的CT表现出许多特征，有助于识别肿瘤的分布和范围。我们得出结论，CT有助于细支气管肺泡癌的诊断和评估。
