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).
Tumors: Tumors are types of brain lesions and may be benign (meningiomas are the most common) or malignant like glioblastoma multiforme. Tumors in the brain may also be metastatic, spreading from cancers that arise primarily from another organ. Symptoms occur depending upon the location and size of the tumor.
