Imaging Analysis on Peripheral Pulmonary Carcinoma Characterized by Solitary Nodular

Objective To explore the clinical value of diagnosis primary peripheral pulmonary carcinoma referring to conventional chest film as well as thoracic CT scan,plain and enhanced.Materials and methods Retrospective analysis on 21cases of solitary peripheral pulmonary carcinoma during 8 years,which are pathologically confirmed by operations and biopsies and with complete data.All patients in the cases,screened by conventional X-ray,have conducted conventional plain CT scan,TLC scanning of the focus zone and enhanced sanning.Imaging analysis on them has carefully made.Results Amongst these 21 cases,there are 9 adenocarcinomas,8 squamous cell carcinomas,3 small cell carcinomas and 1 adenosquamous carcinoma.All of them are malignancy invasion pattern of the lung characterized by pneumonia interstitial type,solitary small nodular type,tumid type,etc.We have found sign of lobulation(7/21),spicule sign(14/21).air bronchograms(8/21),convergence of peripheral vessels(5/21),pleural indentation(4/21)and slipped scattered calcification(2/21).All the pathological changes appear on the periphery of lung.Enhanced scanning in these 21 cases show that the focuses are moderate enhancement and the amplitude of Ctvalue are 20Hu-40Hu.Conclusion It is of great importance to better understand and qualitative diagnose solitary small nodularperipheral pulmonary carcinoma by using conventional X-ray chest film,thoracic CT scan,plain and enhanced,and needle biopsy conducted by CT.The period of clinical observation can be notably shortened and the diagnosis can be timely made.It is also helpful to select therapeutic methods and give prognosis,improving the patients’livability and their quality of life.
