肺癌脑转移瘤在颅内转移瘤中占压倒性多数。随着诊断技术的发展,特别是CT和磁共振(MRI)的应用,肺癌脑转移率呈上升趋势。部分肺患者表现出脑转移症状和脑转移瘤的确诊在前,后经全身检查和追溯原发癌才确诊为肺癌。有学者称这类病征为肺癌脑先行。近5年来我院收治92例肺癌中“脑先行”者占19例,现报道如下。 Brain metastases from lung cancer account for an overwhelming majority of intracranial metastases. With the development of diagnostic techniques, especially the application of CT and magnetic resonance imaging (MRI), the rate of brain metastases in lung cancer is on the rise. Some patients with pulmonary disease showed brain metastases and brain metastases were diagnosed before, and were diagnosed as lung cancer after systemic examination and retrospective diagnosis of primary cancer. Some scholars call this type of disease lung cancer brain first. In the past five years, 92 cases of lung cancer in our hospital have been diagnosed as “preceding the brain.” 19 cases are reported as follows.
