目的探讨临床中细支气管肺泡癌的影像学表现特征和误诊的原因,从而为临床中提高该病的诊断正确率与预后提供有效的参考依据,降低误诊的情况发生。方法采取回顾性方法对秦皇岛市第三医院2006年1月至2012年10月之间收治的50例细支气管肺泡癌患者的临床影像学资料进行分析,并探究不同类型患者的临床表现特征与误诊的基本原因。结果本次研究的CT资料显示,孤立结节型细支气管肺泡癌28例,实变型细支气管肺泡癌19例,多结节型细支气管肺泡癌3例。其中,20例误诊。本组的20例患者误诊,18例患者均为实变型细支气管肺泡癌,其中误诊为肺炎与肺结核。另外2例患者证实为多结节型细支气管肺泡癌,误诊为肺结核,并经手术和肺泡灌洗以及胸穿而证实。结论临床中对于细支气管肺泡癌的影像学的表现特征多一,而且CT诊断能够将该病进行详细的分型,细支气管肺泡癌的影像特征因不同证型而表现不一,在临床诊断中可以借助穿刺活检与纤支镜检进行综合诊断,从而有效的提高该病的临床诊断正确率,减少误诊的情况发生。
Objective To investigate the imaging features and the causes of misdiagnosis of bronchioloalveolar carcinoma in clinical practice, and to provide an effective reference for improving the diagnostic accuracy and prognosis of the disease in clinical practice and to reduce the occurrence of misdiagnosis. Methods The clinical imaging data of 50 patients with bronchioloalveolar carcinoma admitted in the Third Hospital of Qinhuangdao from January 2006 to October 2012 were retrospectively analyzed and the clinical features and misdiagnosis of different types of patients were explored The basic reason. Results The CT data of this study showed that 28 cases of isolated nodular bronchioloalveolar carcinoma, 19 cases of definitive bronchioloalveolar carcinoma and 3 cases of multi-nodular bronchioloalveolar carcinoma. Among them, 20 cases were misdiagnosed. The group of 20 patients misdiagnosed, 18 patients were solid type bronchioloalveolar carcinoma, of which misdiagnosed as pneumonia and tuberculosis. The other 2 patients were confirmed as multi-nodular bronchioloalveolar carcinoma, misdiagnosed as pulmonary tuberculosis, and confirmed by surgery and lavage and chest wear. Conclusions The imaging characteristics of bronchioloalveolar carcinoma in clinic are more than one, and the CT diagnosis can make a detailed classification of the disease. The imaging features of bronchioloalveolar carcinoma vary in different syndrome types. In the clinical diagnosis Can make use of biopsy and bronchoscopy for comprehensive diagnosis, so as to effectively improve the accuracy of clinical diagnosis of the disease and reduce the occurrence of misdiagnosis.
