Clinical analysis of 19 consecutive cases of pulmonary mixed ground-glass opacity nodules
Abstract：Objective To investigate the proportion and diagnostic techniques of pulmonary mixed ground -glass opacity(mGGO), and the relationship between the disease and computed tomography (CT) characteristics. Methods Single mGGO were found in 22 consecutive patients which underwent multi-detector CT.Nineteen ( 86.4%) consecutive cases of mGGO nodules that were histologically confirmed were included in this prospective tri -al.All cases of pulmonary mGGO nodules were divided into two groups:malignant nodules group and benign nodules group.The clinical and radiological characteristics ( including the lesions′size, edge characteristics , internal charac-teristics, etc) of all patients were recorded .These parameters were statistically compared between the two groups .Re-sults There were 4 benign and 15 malignant mGGOs .No statistical differences were found between benign and ma-lignant mGGOs in terms of demographic data , lesions′size, internal characteristics and external manifestations .The frequency of lobulation ( 86.7%) , well-defined interface ( 86.7%) and vascular convergence ( 80.0%) was signifi-cantly higher in malignant mGGOs than that in benign mGGOs .The percentage of GGO component ≤50%was high-er in malignant mGGOs.The diagnostic of 11 cases were confirmed through percutaneous core needle lung biopsy un-der multi-CT fluoroscopic guidance .Conclusion The CT characteristics of pulmonary mGGO nodules have certain significance in the differential diagnosis of lesions properties of pulmonary mGGO nodules .CT fluoroscopy-guided needle aspiration biopsy is a useful diagnostic technique for mGGO nodules .
