Abstract:
Objective To evaluate HRCT typing of solitary pulmonary nodule with resected.Methods 30 cases with solitary plumonary nodules (totally 41) were undergone CT and HRCT scan befor operation.HRCT appearances were retrospectively analyzed and categorized into two types: typeⅠ ground-glass opacity (pure ground-glass opacity, mixed lower opacity, central high opacity with ground opacity ), typeⅡ pure solid opacity.Results TypeⅠ:14 nodules included bronchioloalveolar cell carcinoma (9 nodules) , adenocarcinoma (3 nodules),inflammatory granuloma (1 nodule) and adenoma (1 nodule).TypeⅡ : 27 nodules included adenocarcinoma(13 nodules),bronchioloalveolar cell carcinoma(4 nodules), squamous cell carcinoma(3 nodules),small cell lung cancer(1 nodule),adenoma(2 nodules),tuberculosis(2 nodules), inflammatory granuloma(1 nodule) and hamartoma(1 nodule). Among nodules with resected, ground-glass opacity was found more frequently in bronchioloalveolar cell carcinoma than in non- bronchioloalveolar cell carcinoma (P=0.002).No significant difference in ground-glass opacity existed between tumor lesions and non-tumor lesions (P=0.282) or adenocarcinoma and non-adenocarcinoma (P=0.146).Conclusion In the findings of HRCT in solitary pulmonary nodules,the nodules of ground-glass opacity find more frequently in bronchioloalveolar cell carcinoma than that in other lesions.
