通过5例肺癌脑转移误诊为脑血管病的经验教训,提示(1)临床上对中老年人脑卒中除详细的体格检查外,应常规行头颅CT扫描及胸片检查。(2)脑卒中患者经治疗体征缓解较迅速者(除RIND),应高度怀疑转移癌。(3)临床上遇到不能用脑血管病解释的某一体征者,要考虑到脑转移癌,以提高首发症状为脑血管病的肺癌早期诊断率。 Through 5 cases of lung cancer brain metastases misdiagnosed as cerebrovascular disease experience and lessons, suggesting that (1) In addition to detailed physical examination of stroke in the middle-aged and elderly, should be routinely performed head CT scan and chest X-ray examination. (2) Patients with stroke who are more rapidly relieved by treatment and signs (except RIND) should be highly skeptical of metastatic cancer. (3) Clinically encountered with a physical sign that cannot be explained by cerebrovascular disease, brain metastases must be considered in order to improve early diagnosis of lung cancer with cerebrovascular disease as its first symptom.
