目的回顾性分析实变型肺癌和结核性肺病的CT影像特点,为临床的鉴别诊断提供依据。方法 75例实变型肺癌患者作为肺癌组,75例结核性肺病患者作为结核组,所有患者均采用16排螺旋CT机进行扫描,分析不同病变的CT特征,并对两种疾病的不同特征出现频次进行比较。结果肺癌组和结核组多发肺叶肺段实变(44.0%VS 17.3%)、单发下叶肺段实变(66.7%VS 24.2%)、空洞或空腔(20.0%VS 56.0%)、液化(8.0%VS 65.3%)、充气支气管征狭窄(41.5%VS 17.9%)、实变区周围磨玻璃影边缘清晰(20.3%VS 0)、淋巴结肿大短径<2 cm(100.0%VS 43.8%)比较,差异均具有统计学意义(P<0.01)。结论实变型肺癌和结核性肺病在好发部位、淋巴结肿大<2 cm、是否有空洞和边缘清晰磨玻璃征等因素有显著差异,可供临床上鉴别。
Objective To retrospectively analyze the features of CT images in patients with solid lung cancer and tuberculosis, and provide the basis for the differential diagnosis. Methods Totally 75 patients with lung cancer were enrolled as lung cancer group and 75 patients with tuberculosis as tuberculosis group. All patients were scanned by 16-slice spiral CT scanner, CT features of different lesions were analyzed, and frequency of occurrence of different characteristics of the two diseases Compare. Results Lung cancer group and tuberculosis group had multiple consolidation of lobectomy (44.0% VS 17.3%), single lower lobular consolidation (66.7% VS 24.2%), cavity or cavity (20.0% vs 56.0%), liquefaction 8.0% VS 65.3%), narrow bronchovascular syndrome (41.5% vs 17.9%), clear margins of ground glass around the consolidation zone (20.3% vs 0) Comparison, the differences were statistically significant (P <0.01). Conclusions There is a significant difference between real variant lung cancer and tuberculous pulmonary disease in the incidence sites, lymph node enlargement <2 cm, whether there are empty and marginal clear ground glass signs, which can be clinically identified.
