Recently, the brain glioma center of Sanbo Brain Hospital of Capital Medical University admitted a 7-year-old Zhejiang young patient, Yuanyuan, a skinny and bony little girl weighing only 13 kilograms, who looks like a hungry refugee from the appearance. Yuanyuan’s mother introduced, Yuanyuan three years old after the weight did not increase, four years old after the height did not grow taller. In June this year, round walking walking steps faster and faster, their own uncontrollable forward, until they fell to the ground. At first, the parents just thought the child was too weak, so they increased nutrition for her, and then Yuan Yuan’s appetite decreased, her eyes bulged out, she walked with no strength, and her spirit was very poor, and she developed to the point where she couldn’t walk on her own. The local hospital found that the child’s brain had a huge optic nerve glioma, occupying one-third of the brain space, and combined with hydrocephalus, so the risk of surgery was extremely high, and several major hospitals did not dare to operate. They finally found Professor Lin Zhixiong, a pediatric neurosurgeon from Sanbo, who admitted Yuanyuan, who was already in a state of coma, to the hospital. After careful preparation, Yuanyuan underwent tumor resection surgery, which was very successful, relieving the hydrocephalus problem, completely cutting the brain tumor, and protecting the important brain tissues intact. Yuanyuan recovered well after the surgery. Professor Lin introduced: Yuanyuan’s tumor grew on the optic nerve and invaded the frontal area, hypothalamus and saddle area, the location is very deep and the surrounding brain tissues are all important functional areas, the surgery is very difficult and the risk of disability and death is extremely high. Professor Lin reminded that there are various manifestations of brain tumors, such as damage to vision and hearing, intellectual decline, dizziness and vomiting, unsteady walking, etc. In addition, extremely low or heavy weight should also attract parents’ attention.
