PXA is diagnosed through a combination of diagnostic processes:
Initially, a doctor will interview the patient and do a clinical exam, which will include a neurological examination.

A CT scan of the brain, and/or an MRI scan of the brain and spine, will be performed.
A special dye may be injected into a vein before these scans to provide contrast and make tumors easier to see.

For children experiencing seizures, an EEG might be part of the diagnostic process (the goal being to record the brain's electrical activity in order to identify and localize seizure activity).

Finally, a biopsy of the tumor, taken through a needle during a simple surgical procedure, helps to confirm the diagnosis.
