The group of 5 patients, 2 males and 3 females. Age 11 to 15 years old (average 13.4 years old). Duration of 1 to 3 years, an average of 2 years. Visual acuity were visual field disorders, with polyhydration, polygamy, gigantism, dwarfism and central obesity, cranial nerves of the third, the fourth and the fifth lesions. 5 cases were performed skull X-ray and contrast examination, showed a significant increase in the sella, saddle back thinning, double saddle at the end. Slow air-brain angiography shows the saddle has soft tissue block shadow, the front of the third ventricle compression, optic chiasm pool forward or poorly inflated, foot pool after the shift. Carotid angiography showed the A 1 segment elevation, bilateral internal carotid artery C 2-C 4 segment to the lateral shift. This group all using surgical treatment. Surgery see the tumor was dark red or gray, protruding to the front of the optic chiasm, optic nerve compression becomes thinner, outward shift. 1 case of puncture out of old blood 6ml. The tumor is soft and easy to resect. 1 case of hard to intracapsular block resection, up to the naked eye the next full or full cut, and part of the excision of the tumor wall open, burning the tumor wall
