Abstract：Objective To improve the diagnostic accuracy of single inflammatory nodules and avoid unnecessary surgery.Methods Retrospective analysis of HRCT features in 51 patients with solitary inflammatory pulmonary nodules that resolved fol-lowing surgical and medical treatment was conducted.Results Of the 51 cases in this group,36 were located in the right lung,including 7 cases in the upper lobe,6 cases in the middle lobe,and 23 cases in the lower lobe;the remaining 15 cases were lo-cated in the left lung,including 7 cases in the upper lobe,8 cases in the lower lobe.There were 3 cases with a size≤10 mm,4 cases with a size 10 to≤20 mm,and 44 cases with a size>20 mm.There were 46 cases of pure ground-glass nodules and 5 cases of partially ground-glass nodules.The morphology showed round or oval shape in 5 cases,irregular shape in 18 cases,patchy shape in 26 cases,and multinodular fusion in 2 cases.The edge of the lesion was clear in 5 cases and blurred in 46 cases.Patent bronchi with a natural course was identified within the lesions in 48 cases,while,mild bronchial dilation was noted in 3 cases.Adjacent pleural thickening was present in 19 cases,with inflammation adhering to the pleura and forming knife-cut mar-gins in 13 cases.Thickening of perinodular bronchial walls was observed in 47 cases,accompanied by surrounding alveolar in-flammatory changes in 17 cases.Both features,i.e.,bronchial wall thickening and alveolar inflammation,coexisted in 13 cases.Following anti-inflammatory treatment,lesion size reduction or complete resolution occurred in 48 cases,while,no significant changes were observed during follow-up in 3 cases.Conclusion According to the analysis of the cases in this group,the mor-phology of ground-glass nodules is irregular and patchy,with blurred edges,and the internal bronchial obstruction is naturally in-flammatory nodules.Thickening of the bronchial wall around the nodule and inflammation of the surrounding alveoli can also be used as a basis for the diagnosis of inflammatory nodules.
