Objective: To investigate the relationship of computed tomography(CT) findings with benign or malignant features of solitary pulmonary ground-glass opacity(sp GGO). Methods: CT characteristics including tumor size, internal characteristics(ovule sign, air bronchograms), lobulation, burr, pleural indentation and closing the vessel convergence sign and pathological diagnosis were retrospectively analyzed with 196 patients of solitary pulmonary ground-glass opacity that was coni rmed by histopathology. The data were analyzed to summarize the relationship between CT findings and GGO features. Results: The existence of ovule sign and air-bronchogram of the lesions were no statistically significant differences between benign and malignant GGOs(P0.05). Lobulation, burr, pleural indentation and closing the vessel convergence sign were significantly different between benign and malignant GGOs(P0.05). Conclusion: The longer the diameter of GGO, the higher the possibility of malignancy. CT characteristics including lobulation, burr, pleural indentation and closing the vessel convergence sign can be used as the specific signs of malignant GGO.
