Abstract:
Objective To compare the spiral CT and pathological findings of sub-centimetre pulmonary ground glass nodules(GGNs), and to improve the aaccuracy in early diagnosis.Methods The CT findings and pathologic features of 30 patients with sub-centimetre pulmo-nary GGNs in our hospital from May 2013 to June 2016 were reviewed retrospectively.The patients were divided into 3 groups according to their pathological classification,namely the benign group,the preinvasive group and the invasive group.The shape,size,margin,vacuole sign, pleural indentation,the relations with bronchi and blood vessels of the pulmonary GGNs were analyzed.Results There was no significant difference in shape,maximum diameter and margin between the benign group and the other two groups(P>0.05).Adjacent vessels changes of the lesion showed significant differences between benign group and preinvasive or invasive groups(P<0.05).And there were significant differences in size,pleural indentation,vacuole sign and adjacent vessels changes between the preinvasive group and the invasive group(P<0.05).Conclusion The comprehensive analysis of lesions size,vacuole sign,pleural indentation and adjacent vessels changes can be helpful to improve the aaccuracy of differential diagnosis on sub-centimetre pulmonary ground glass nodules.
