目的探讨64排容积CT扫描在炎性肺泡癌中的鉴别诊断价值。方法 2011年5月至2012年5月期间,我院诊治的60例炎性肺泡癌患者,通过GE Light Speed VCT螺旋CT扫描机,进行CT扫描检查,对其影像学资料进行回顾性分析。结果 60例炎性肺泡癌患者中,30例孤立结节型,20例肺叶实变型,10例多发结节型。30例孤立结节型肺泡癌患者中,25例表现为磨玻璃征(83.3%),24例表现为支气管充气征(80.0%),23例表现为分叶征(76.7%),以及20例表现为毛刺征(66.7%)。20例肺叶实变型肺泡癌患者中,17例表现为枯树枝型(85.0%),15例表现为蜂房征(75.0%),12例表现为叶间胸膜膨出(60.0%)。根据病理分型,60例炎性肺泡癌患者中,40例非粘液型、17例粘液型,以及3例混合型。结论对于炎性肺泡癌的临床诊断,64排容积CT扫描可以提供较为准确的辅助诊断依据,临床医师必须根据CT结果,与其他疾病进行鉴别诊断后,做出最终的临床诊断。
Objective To investigate the differential diagnosis value of 64-row volume CT scan in inflammatory alveolar carcinoma. Methods From May 2011 to May 2012, 60 patients with inflammatory alveolar carcinoma diagnosed and treated in our hospital were examined by CT scan with GE Light Speed VCT spiral CT scanner. The imaging data were retrospectively analyzed. Results Of the 60 patients with inflammatory alveolar carcinoma, 30 were isolated nodules, 20 were solidified and 10 were nodules. Of the 30 patients with isolated nodular alveolar carcinoma, 25 showed bronchoscopic signs (83.3%), 24 showed signs of bronchial inflamation (80.0%), 23 showed lobulation (76.7%), and 20 Show as burr sign (66.7%). Of the 20 patients with solidified alveolar carcinoma of the lung, 17 showed dead branches (85.0%), 15 showed bee hives (75.0%) and 12 showed interstitial pleuropneumonia (60.0%). According to the pathological classification, 60 patients with inflammatory alveolar carcinoma, 40 non-mucus type, 17 mucinous type, and 3 mixed type. Conclusion For the clinical diagnosis of inflammatory alveolar carcinoma, the 64-row volume CT scan can provide a more accurate basis for the diagnosis of ancillary diseases. Clinicians must make the final clinical diagnosis based on the CT results after differentiating them from other diseases.
