Patient: Description of the condition (onset time, main symptoms, hospital visited, etc.): Hello Dr. Yuan, I am a Chongqing girl who came to see you for my son on Monday, my son’s name is Li Zhilin, now one year and two months, I took the film to see you, do you remember? He has an arachnoid cyst, and I came back to see Director Luo later (Luo. A. But now I’ve come back and heard my mother say that my son’s headache is getting worse these days, and he’s hitting his head with the remote control, and the number of times he’s fighting has increased significantly. Should we do surgery right away, but the director of Aigo said he is still too young to do a shunt yet, so what should we do? Should we continue to observe? Thank you! Beijing Tiantan Hospital Neurosurgery Department: If possible, try to observe for a while, and it is best to wait until the child is older before doing the bypass surgery. If that is not possible, then consider direct surgery. Try to give me a call for consultation. Patient: Yes, thank you very much. I will call you directly if I have any questions in the future! Beijing Tiantan Hospital Neurosurgery Department: Welcome!
