Vision loss and dizziness may be precursors of intracranial tumors. Experts mentioned that intracranial tumors in many cases lie in patients’ own lack of attention. “Usually, when dizziness and vertigo are not intense and there is no nausea or vomiting, the patients themselves do not perceive them, and coupled with the fact that vision loss is also easily overlooked, many people are not discovered by chance until they visit the doctor with near blindness on one side or other symptoms.” “In addition, due to the lack of children’s expression ability and the lack of experience of some parents, when typical clinical symptoms, even symptoms such as increased intracranial pressure, appear before diagnosing intracranial tumor, often the tumor is already relatively large, and the risk of surgery and the difficulty of preserving neurological functions will increase.” Experts remind that it is important to have enough knowledge about the early manifestations and symptom evolution of pediatric intracranial tumors, so as to achieve early diagnosis and treatment as much as possible.
