目的为早期诊断和合理治疗颅内转移肿瘤提供临床依据方法对１３６例颅内转移性肿瘤原发灶和转移灶的关系、病理类型、临床和影像学表现、治疗方法和疗效进行回顾分析。结果（１）肺癌、消化系癌和乳腺癌最常发生颅内转移；（２）颅内转移癌最常见的为腺癌、鳞癌和未分化癌；（３）发现原发肿瘤到出现脑转移症状大多不到半年；（４）脑转移癌首发症状主要为头痛、偏瘫和精神障碍；（５）脑转移癌ＣＴ和ＭＲＩ增强扫描都表现强化效应，都存在瘤周水肿；（６）单发脑肿瘤手术加放疗有显著效果。结论（１）癌症患者一理出现神经系统症状时，应进行ＣＴ或ＭＲＩ检查明确颅内转移；（２）颅内转移癌应尽量争取手术和放谢治疗。
Objective To provide a clinical basis for the early diagnosis and rational treatment of intracranial metastases in 136 cases of intracranial metastases of primary tumor and metastasis, pathological type, clinical and imaging findings, treatment and efficacy were retrospectively analyzed. Results (1) Most intracranial metastases were found in lung, digestive and breast cancers. (2) The most common intracranial metastases were adenocarcinoma, squamous cell carcinoma and undifferentiated carcinoma. (3) (4) The main symptoms of brain metastases are headache, hemiparesis and mental disorders; (5) CT and MRI enhanced scanning of brain metastases show enhanced effect, all have peritumoral edema; (6) single Brain tumor surgery plus radiotherapy have a significant effect. Conclusions (1) Patients with cancer who appear nervous system symptoms, CT or MRI examination should be clear intracranial metastases; (2) intracranial metastases should strive for surgery and radiotherapy Xie treatment.
