目的探讨肺癌不典型征象CT表现,加强对不典型征象的肺癌的认识,提高不典型征象的肺癌的诊断水平,减少误诊。方法对不典型征象肺癌的临床病例以及CT表现进行回顾性分析,选择经支气管镜检、手术切除、肺内病变穿刺活检后病理检查、痰细胞检查证实的不典型CT征象肺癌15例,左肺上叶2例,下叶3,右肺上叶2例,中叶3例,下叶4例,同时累及右肺中下叶1例。结果不典型征象肺癌CT表现无特异性,很多表现与肺结核、肺炎、肺脓肿及错构瘤等肺部疾病共有。结论常规螺旋CT、HRCT及增强扫描可以对病灶中的细节特征及血供有良好显示,成为鉴别肺部良恶性病变主要影像学方法。
Objective To investigate the CT findings of atypical signs of lung cancer, to strengthen the understanding of atypical signs of lung cancer, to improve the diagnosis of atypical signs of lung cancer and to reduce misdiagnosis. Methods A retrospective analysis of clinical manifestations and CT findings of atypical lung cancer was performed. Fifteen patients with lung cancer, including atypical CT findings confirmed by pathological examination after bronchoscopy, surgical resection and biopsy of lung lesions, left lung 2 in the upper lobe, 3 in the lower lobe, 2 in the upper lobe of right lung, 3 in the middle lobe, 4 in the lower lobe, and 1 in the middle and lower lobe of the right lung. Results atypical signs of lung cancer CT showed no specificity, many performance and tuberculosis, pneumonia, lung abscess and hamartoma and other lung diseases. Conclusion Conventional spiral CT, HRCT and enhanced scan can display the detail features and blood supply of the lesion well and become the main imaging method to differentiate the benign and malignant lung lesions.
