Intracranial tumours represent about 2% of all cancers. There are no known risk factors apart from prior irradiation to the skull and brain and a few rare neurogenetic syndromes (e.g. neurofibromatosis, von Hippel–Lindau syndrome, Li–Fraumeni syndrome). They may be intrinsic or extrinsic, which determines potential resectability. Neuroepithelial tumours (predominantly gliomas) account for 50–60% of all primary tumours. Molecular analysis has now been added to the histological grade and subtype to provide an integrated diagnosis which provides more accurate information for treatment and prognosis. As systemic anti-cancer treatments evolve and produce long-term control of visceral and bone disease, brain metastases are becoming increasingly common and are best treated with feither stereotactic radiosurgery or neurosurgery to avoid the cognitive decline associated with whole brain radiotherapy.
