Intracranial metastases

Intracranial Metastatic Tumors are metastatic tumors of other parts of the body that have metastasized to the skull. Cancer, sarcoma and melanoma can all metastasize to the skull. Most of the intracranial metastases seen clinically are metastatic carcinoma, accounting for more than 90%. There are three ways for the malignant tumor to metastasize into the skull: ① menstrual blood flow, ② lymphatic, and ③ direct invasion, among which menstrual blood flow is the most common route. The metastatic pathway and site are related to the site of the primary tumor. Such as lung cancer, breast cancer, skin cancer and other major blood flow metastasis, easy to form multiple metastatic cancers in the brain, those without treatment are more likely to die quickly. Gastrointestinal cancers are more likely to metastasize through the lymphatic system and spread to the meninges.
