The bridge of the brain is often referred to as the pontine brain in clinical practice. The pontine brain is a high incidence site for brainstem gliomas, which are more prevalent in children, and the tumors are diffuse. The development of the disease is insidious, that is, when the clinical manifestations are obvious, the tumor is already large. The common clinical symptoms are unsteady walking and distorted eyes and mouth. However, the early symptoms of the disease are not obvious, and the child has no obvious headache and lives a normal life. When the family notices that the child has symptoms such as wobbly walking, poor balance, and distorted eyes, the child will go to the doctor for nuclear magnetic detection, which often shows that the tumor is large.
