Craniopharyngioma

A craniopharyngioma is a rare, noncancerous (benign) brain tumor that usually develops near the pituitary gland and the hypothalamus. Although slow-growing, its location near critical structures can cause significant hormonal, vision, and neurological issues.

What Is Craniopharyngioma?

Craniopharyngiomas arise from embryonic remnants of Rathke's pouch along the pathway of the pituitary gland. They are technically benign (WHO grade 1) but behave aggressively locally, often compressing the optic nerves, pituitary stalk, and hypothalamus. They typically contain fluid-filled cysts and calcifications.

At a Glance

Rare, benign tumors developing near the pituitary gland
Bimodal age distribution: peaks in childhood (5-14 years) and adulthood (50-74 years)
Commonly causes visual field deficits and hormonal imbalances
Maximal safe surgical resection is the primary treatment
Often requires multidisciplinary care including neurosurgery, endocrinology and neuro-ophthalmology

Symptoms

Diagnosis

Types

Treatment

Endoscopic Endonasal Approach (EEA) — a minimally invasive procedure through the nose to remove the tumor, increasingly the preferred method for tumors extending into the suprasellar space.
Open Craniotomy — traditional surgical approach required for very large tumors or those extending laterally beyond the reach of an endoscope.
Radiation Therapy — used for residual tumor to prevent recurrence, or for tumors that cannot be safely resected without causing severe neurological or hypothalamic damage.
Hormone Replacement Therapy — often required lifelong after surgery to manage pituitary dysfunction.

Outcomes

Treatment Strategy	10-Year Survival Rate	Notes
Gross total resection	~85-90%	High cure rate but carries higher risk of endocrine and hypothalamic deficits
Subtotal resection + Radiation	~80-90%	Excellent tumor control with potentially lower risk to adjacent critical structures
Subtotal resection alone	Lower	High rate of tumor recurrence; adjuvant radiation is highly recommended
