Diagnosis By Mayo Clinic Staff Print 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. Request an appointment Diagnosis & treatment Aug. 19, 2025 Print Share on: FacebookTwitter Living with craniopharyngioma?
