Craniopharyngiomas are the commonest benign histological tumours to involve the hypothalamo-pituitary region in childhood. Cystic craniopharyngiomas occur in more than 90% of tumours. The optimal treatment of cystic craniopharyngioma remains controversial. Radical resection is the treatment of choice in patients with favourable tumour localization. When the tumour localization is unfavourable, a gross-total or partial resection followed by radiotherapy is the main treatment option in adults. However, it presents risk of morbidity especially for children. Intracystic bleomycin has been utilized to potentially delay the use of radiotherapy or radical resection to decrease morbidity.
