Ground glass appearance of solitary nodules of bronchioloalveolar carcinoma CT diagnosis / 中国基层医药

ABSTRACT

Objective To investigate the ground glass appearance of solitary nodules of bronchioloalveolar carcinoma of the CT imaging features.Methods A retrospective analysis of 20 cases with pathologically proved with a ground glass appearance of solitary nodules of bronchioloalveolar carcinoma of the clinical and imaging data of CT.Results 20 cases of solitary nodules of bronchioloalveolar carcinoma without obvious clinical symptoms ;locationthe upper lobe of the left lung in 10 cases,right upper lobectomy in 5 cases,3 cases of the right middle lobe,lower lobe of the left lung in 2 cases; all lesions were located at the lung periphery,both ground glass opacity nodules,14 of them patients with lesions of the peripheral see spiculation in 5 cases,vacuole sign,8 cases with air bronchogram,16 cases with pleural indentation,10 cases of vascular convergence sign etc..In 20 cases the lesion enhancement scan after the lesion showed no enhancement.In all cases,through the CT dynamic observation,no obvious change in lesion size,lesion slightly higher density,finally performed lobectomy pathologically diagnosed non mucoid alveolar cell carcinoma.Conclusion the ground glass appearance of solitary nodules of bronchioloalveolar carcinoma progress is slow,dynamic imaging observation helps to confirm the diagnosis.
