<prompt> All of the following statements are true regarding craniopharyngioma, except:Origin from Rathkes pouchAggressive malignant tumorPapillary variant of the tumour is associated with BRAF V600E mutationAdamantinomatous variant is associated with abnormality in WNTCTNNB1 b-catenin pathway  <response>: Craniopharyngioma Arise from vestigial remnants of Rathkes pouch. Slow-growing benign tumors Accounts 1 to 5 of intracranial tumors. Minority of these lesions occurs within sella, but most are suprasellar with without intrasellar extension. Adamantinomatous craniopharyngioma - Abnormalities of WNT signaling pathway, activating mutations of gene encoding b-catenin. Papillary subtype is characterized by activating mutations of the BRAF oncogene at codon 600 V600E.
