【摘要】 目的　评价肺癌肺内转移在CT影像上的各种形态表现。方法　194例病例,其中男106例,女88例,平均45岁。原发肿瘤包括鳞癌56例(28. 9% ),腺癌107例(55. 2% ),小细胞肺癌26例(13. 4% ),腺鳞癌5例(2. 6% )。结果　肺癌肺内血行转移主要以实性结节最为常见,其少见影像可表现为空洞转移、磨玻璃转移、转移病灶边缘毛糙和/或胸膜凹陷征以及转移灶内可见含气支气管气像,并主要见于肺腺癌;淋巴道转移表现为支气管血管束不规则结节状增厚,小叶间隔增厚呈串珠状或胸膜下多角形细线结构。结论　肺癌肺内转移可呈多形性影像表现。更多还原

【Abstract】 Objective To describe varied features of pulmonary metastases of lung cancer on CT imaging .Methods 194 patients with pulmonary metastases of lung cancer were evaluated on CT scan , including 106 men and 88 women . The median age of the patients was 45 years ( range from 22 to 78 years ) . The histology of the lung cancer included 56 squamous carcinomas(28.9%),107 adenocarcinomas(55.2%),26 small cell carcinomas(13.4%),and 5 adenosquamous carcinomas(2.1%).Results The usual pattern of pulmonary metastases of lung cancer were parenchyma nodules. The unusual form of metastases that were mainly found in adenocarcinomas were cavitary lesions, ground-glass nodules and lesions with unusual signals including lobulated structure, spiculated margin,pleural indentation and air-bronchogram. The manifestations of lymphangial spread to intrapulmonary were extensive uneven thickening of the interlobular septa and fissures, nodular thickening of brochovascular bundles and many fine nodulars distributed along the brochovascular bundles and interlobular septa.Conclusion The manifestations of intrapulmonary metastases of lung cancer are varied morphologic features.更多还原
