The spiral CT differential diagnosis of pulmonary inflammatory mass and peripheral lung carcinoma / 重庆医科大学学报

ABSTRACT

Objective:To investigate the CT manifestations of pulmonary inflammatory mass and peripheral lung carcinoma,and to improve the differentiation of the diseases.Methods:The CT manifestations of 26 cases of pulmonary inflammatory masses and 38 cases of peripheral lung carcinomas were retrospectively analyzed.All cases were proved by pathological or clinical appearances.The masses were divided into typical and atypical masses according to morphology.Studying the CT signs of lesions and combining them with the results of morphological classification improve diagnosis of the morphological classification.Results:According to the morphological classification of masses,the diagnostic sensitivity,specificity and accuracy of inflammatory mass were 65.4%,73.7% and 70.3% respectively.The improved sensitivity,specificity and accuracy were 80.8%,86.8% and 82.8% respectively.Conclusion:Combining the results of morphological classification of masses with the CT signs of lesions have important value in the differentiation of pulmonary inflammatory mass and peripheral lung carcinoma.
