Diagnosing a craniopharyngioma usually starts with a medical history review and a discussion of symptoms. Tests used to diagnose a craniopharyngioma include:
- Neurological exam. During this exam, a healthcare professional tests vision, hearing, balance, coordination, reflexes, and growth and development. This can help show which part of the brain might be affected by the tumor.
- Blood tests. Blood tests may reveal changes in hormone levels that show a tumor is affecting the pituitary gland.
- Imaging tests. Imaging tests capture pictures of the brain. The pictures can show the size and location of the tumor. Imaging tests include X-rays, CTs and MRIs. In certain situations, other tests might be needed.
