Abstract:
Objective To analyze the imaging features of solitary pulmonary nodules (SPN).Methods The clinical data and chest imaging features of 55 cases with SPN confirmed by pathology were retrospectively analyzed . Results Of the 55 patients,40 cases (80.00％) were lung cancer and 15 cases (20.00％) were benign lesions . The univariate analysis showed that the age of patients (t=2.972,P=0.004),lobulation sign (χ2 =7.018,P=0.008) and pleural indentation sign (χ2 =4.727,P=0.030) had statistically significant differences in distinguish of the benign and malignant nodules ,but the sex (χ2 =1.760,P=0.185),nodule site (χ2 =0.145,P=0.703),burrs (χ2 =0.555,P=0.456),cavity (χ2 =0.000,P=1.000),nodule size (t=0.608,P=0.546) and other factors had no significant difference.Multivariate Logistic regression analysis showed that age (OR=1.101,P=0.022) and lobulation sign (OR=6.187,P=0.026) were independent influencing factors for judgement of the benign and malig -nant SPN.Conclusion The age of patients,lobulation sign and the pleural indentation sign are related to the benign and malignant SPN .Age and lobulation sign are the independent influencing factors for judgement of the benign and malignant SPN .
