Overview
A craniopharyngioma is a benign (non-cancerous) tumor that develops near the pituitary gland and the base of the brain. Although it is not a cancer, its location next to the optic nerves, the pituitary, and the hypothalamus means it can cause important problems with vision, hormones, and other functions.
Craniopharyngiomas can occur in children and adults. Common features include vision changes, headaches, hormonal symptoms such as excessive thirst and urination or growth and energy changes, and, in some cases, effects on appetite and weight regulation from involvement of the hypothalamus.
Management is highly individualized and multidisciplinary, drawing on neurosurgery, endocrinology, and, when an endonasal approach is appropriate, skull-base rhinology. Treatment may include surgery, radiation, and long-term hormonal and visual follow-up. This page is educational and does not replace specialist evaluation.
What craniopharyngioma is
A craniopharyngioma is a benign tumor that arises near the pituitary gland and the base of the brain, often in the area above and around the pituitary. Although benign, it can be locally challenging because it sits next to the optic nerves, the pituitary, and the hypothalamus.
Vision, hormonal, and hypothalamic symptoms
Because of its location, a craniopharyngioma can compress the optic pathways and cause vision changes, affect the pituitary and lead to hormonal symptoms such as excessive thirst, fatigue, or growth changes, and involve the hypothalamus, which can affect appetite, weight, and temperature regulation. Headache is also common.

MRI and endocrine evaluation
MRI is the main imaging test to define the tumor and its relationship to surrounding structures, and CT can add information about calcification. A thorough hormonal (endocrine) evaluation and formal vision testing are important to document how the tumor is affecting these systems before and after treatment.
Observation, surgery, and radiation
Management is individualized. Some situations are observed, while others are treated with surgery, radiation, or a combination. The plan depends on the size and location of the tumor, the symptoms it is causing, and the patient's overall health, and it is made by a multidisciplinary team.
Endoscopic versus open routes
When surgery is chosen, some craniopharyngiomas can be approached endoscopically through the nose (an endonasal route), while others require an open approach. The route depends on the tumor's exact location, its extension, and its relationship to nearby nerves and vessels. The goal is to relieve pressure and obtain tissue while protecting vital structures.

Long-term endocrine and visual follow-up
Because the tumor and its treatment can affect hormones and vision, long-term follow-up with endocrinology and vision testing is important. Hormone replacement is managed by endocrinology when needed, and imaging is used to monitor for recurrence.
When to seek care
Seek prompt evaluation for new or worsening vision changes, severe or persistent headache, excessive thirst and urination, or unexplained fatigue. Seek emergency care for sudden vision loss, severe headache, confusion, or vomiting, which require immediate attention.
