The terms benign and pseudotumor derive from the fact that increased intracranial pressure may be associated with brain tumors. Those patients in whom no tumour was found were therefore diagnosed with pseudotumor cerebri (a disease mimicking a brain tumor).
A primary brain tumor is a tumor which begins in the brain tissue. If a cancerous tumor starts elsewhere in the body, it can spread cancer cells, which grow in the brain. These type of tumors are called secondary or metastatic brain tumors.
