Tests and procedures used to diagnose craniopharyngioma include:
- Physical exam. Diagnosing a craniopharyngioma usually starts with a medical history review and a neurologic exam by your doctor. During this procedure, your vision, hearing, balance, coordination and reflexes are tested.
- Blood tests. Blood tests may reveal changes in hormone levels that indicate a tumor is affecting your pituitary gland.
- Imaging tests. Tests to create images of your brain may include X-rays, magnetic resonance imaging (MRI), a computerized tomography (CT) scan or a positron emission tomography (PET) scan.
