摘　　要：目的通过对肺炎性假瘤的CT征象进行分析,积累此疾病的CT诊断及减少其误诊的经验。方法对8例经病理证实为肺炎性假瘤患者的CT征象进行回顾性分析。结果肺炎性假瘤的较典型CT表现为:病灶多位于肺野外周,形态多样,边缘见毛刺或棘状突起(桃尖征);病灶内见不规则钙化影或小空洞;病灶边缘可见尖角状粘连(尖角征)及刀切样改变;肺门及纵隔内无明显肿大淋巴结;增强扫描,病灶强化明显;动态观察,病灶长时期无变化,少数病灶经治疗后可缩小。结论掌握肺炎性假瘤的较典型CT表现并充分结合临床资料可提高肺炎性假瘤影像诊断的正确率,减少误诊。Objective To investigate the CT features and value in diagnosing pulmonary inflammatory pseudotumor.Methods The CT imaging features of 8 cases of pathological diagnosis confirmed by pathology were analysed retrospectively.Results The main CT findings were as follows:①The lesions were usually located peripheral pulmonary,the shape is diverse,briquetting shade,the edge have the burr;②Irregular shape calcification and small cavities can be seen in the lesions;③The lesions near to pleurae had localized pleural thickening and adhesion;④Hilar and mediastinal lymphonodies had no enlargement;⑤Takes the CT enhancement scanning,the focus of infection strengthens many is obvious;⑥Makes a follow-up visit,the lesions had no changes,minority cases after treatment may reduce to the absorption.Conclusion Grasp the typical diagnosis of pulmonary inflammatory pseudotumor by computed diagnosis,unify infects the medical history formerly can be helpful to get great raise the diagnostics accuracy of this disease,and reduce misdiagnosis.
