​The doctor will take history from the patient and perform a physical examination.

Imaging tests such as the Computed Tomography (CT) scan and Magnetic Resonance Imaging (MRI) may be done.

At times, special tests like a Cerebral Angiogram (x-rays of the blood vessels in the brain), Functional MRI scans and
an MRI Tractography may be needed.

These tests help to pinpoint the tumour’s size and site, and how close it is to the parts of the brain that controls key functions like speech. The test results will help the neurosurgeon to plan for removal of the tumour.
