Craniopharyngioma.

Craniopharyngiomas are rare epithelial tumors arising along the path of the craniopharyngeal duct; therefore, they occur in the sellar or suprasellar regions. These tumors commonly lead to neurologic, endocrinological, or visual symptoms. Radical surgery is the treatment of choice in craniopharyngiomas. The transnasal/transsphenoidal endoscopic approach offers the possibility of removing the tumor without retracting brain and optic pathways, with good results. The rate of cerebrospinal fluid fistula has improved due to the use of vascularized mucosal flaps for cranial base reconstruction.
