Various types of brain tumors may cause hemorrhage. Increased tumor vascularization with dilated, thin-walled vessels and tumor necrosis are the most important mechanisms of hemorrhage. There are many potential brain tumors which can lead to hemorrhage, thus, the below lists are not exhaustive.
Pathology
Primary tumors
Secondary tumors
Hemorrhagic intracranial metastases are considered to represent between 3-14% of all cerebral metastases (cf. 1-3% of gliomas are hemorrhagic).
These can be recalled with the mnemonic MR CT BB.
