The results of imaging studies (computerized tomography scans and magnetic resonance imaging [MRI] scans) are often diagnostic for craniopharyngiomas, with most demonstrating intratumoral calcifications. Craniopharyngiomas without calcification may be confused with other tumor types, such as germinoma or hypothalamic/chiasmatic astrocytoma, and biopsy may be required.[1] Magnetic resonance spectroscopy may be diagnostically helpful in some cases.[2] MRI of the spinal axis is not routinely performed.

Apart from imaging, patients often undergo formal visual examination including visual field evaluation, and endocrine testing.
