First Local Experience of Intra-Cavitary Yttrium-90 Citrate Colloid Irradiation via Ommaya Reservoir for Refractory Cystic Craniopharyngioma: a Case Report.

Craniopharyngioma is uncommon benign intracranial tumour that can be cured by surgical resection followed by conventional radiotherapy. However, its anatomical localisation makes the treatment hazardous or impossible. This case report aims to discuss the first local experience of using beta-emitting Yttrium-90 radioisotope in treating a patient with refractory cystic craniopharyngioma.
