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.
