目的:讨论肺孤立结节患者的临床特点及影像学表现。方法:回顾分析我科68例肺孤立小结节患者的临床资料,对其临床特点及影像学表现进行统计分析,计算主要辅助检查诊断的准确率。结果:68例患者中,肺恶性肿瘤34例(50%),肺良性肿瘤16例(23.53%),肺结核球18例(26.47%)。随着结节直径增大,肺癌的发生率增高。胸部X线诊断的准确率为38.24%,胸部CT诊断的准确率为75%,纤维支气管镜检查准确率为13.64%,痰细胞学检查准确率为7.89%。结论:肺部孤立结节是一组病因复杂的疾病,其中恶性病变约占50%,诊断上仍有一定困难。治疗上应及早手术,彻底切除病变,尽量保存肺组织。 Objective: To discuss the clinical features and imaging findings of isolated pulmonary nodules. Methods: The clinical data of 68 patients with solitary pulmonary nodules in our department were retrospectively analyzed. The clinical features and imaging findings were analyzed statistically. The accuracy of the main auxiliary examinations was calculated. Results: Of the 68 patients, 34 (50%) had malignant lung tumors, 16 (23.53%) had benign lung tumors and 18 (26.47%) had tuberculous spheroids. As the nodule diameter increases, the incidence of lung cancer increases. The diagnostic accuracy of chest X-ray was 38.24%, the diagnostic accuracy of chest CT was 75%, the accuracy of fiberoptic bronchoscopy was 13.64% and the accuracy of sputum cytology was 7.89%. CONCLUSIONS: Pulmonary solitary nodules are a complex group of diseases with malignant lesions accounting for about 50%. There are still some difficulties in diagnosis. Treatment should be as early as surgery, complete removal of the lesion, try to save the lung tissue.
