Ventricular metastatic dissemination of a paediatric craniopharyngioma: case report and literature review.

Distant intraventricular metastasis is extremely rare in childhood craniopharyngioma. Here, we report the isolated posterior ventricular recurrence of an adamantinomatous craniopharyngioma, in a child previously treated with surgery and proton beam therapy for local progression. The importance of surveillance imaging is highlighted, while specific surgical approaches and techniques are considered.
