Craniopharyngiomas are very rare benign (non-cancerous) tumours, with 50% occurring in children under 16 years, and the remainder at any time in adult life.

The tumours can be solid, cystic (full of fluid), calcified, or full of debris. They are slow-growing tumours that can take 2-3 years (or longer) to manifest themselves before a diagnosis is made.
