Lynch-, Turcot- and Li-Fraumeni syndrome all come with a higher risk of developing a glial tumor (4). To date the etiology of gliomas is not clear. However, several factors such as genetic background, immulogical factors and infections have been sug-gested to play a role (5). SEER (Surveillance, Epidemiology, and End Re-

Concordance between local diag-nosis and central neuropathology review can be as low as 50%, thus careful review of the histology by an expert neuropathology team is recommended [5, 6].

Other changes included the addition of brain invasion as a criterion for atypical meningioma and the introduction of a soft tissue-type grading system [Louis et al., 2016].

Anaplastic astrocytomas occur more often in younger adults ages 30 -50 and account for 17% of primary malignant brain tumors. Only 9% of childhood brain tumors are glioblastomas. Between 1% and 7% of people with glioblastomas and about 4% of people with anaplastic astrocytomas are found to have multiple tumors at the time of diagnosis. CAUSE
