Craniopharyngioma is a benign tumor characterized by cystic and calcification, surrounded by vital structures therefor it is difficult to perform total tumor resection. Combination with Gamma knife radiosurgery (GKRS) is the best treatment option. The complexities of GKRS consisting of several phases lasts for 6-10 hours. Anesthesia is needed for uncooperative patients. This is a case of a 4-year-old girl with cystic craniopharyngioma. The patient had chief complaint of blurry vision, physical examinations revealed bilateral papil atrophy. Result of MRI showed tumor mass compressing inferior hypophyse. Patient underwent the procedure under moderate sedation with Propofol at 75 mcg/kg/min for 6 hours. Intraoperative hemodynamic condition was stable without adverse events. Choice of anesthesia either general anesthesia or sedation, depends on the condition of patient, considerations from anesthesiologist dan neurosurgeon, dan availability of facilities. Unique considerations for GKRS are; a non-operating room anesthesia, long duration, transportation to other units such as radiology and cathlab, head of the patients need to be immobilized to prevent frame displacement, the patient will be alone in the treatment room, and principles of pediatric anesthesia and neuroanesthesia.
