Expert interpretation: the clinical symptoms of benign brain tumors need to be understood.

Headache is the earliest and most common symptom of benign brain tumors, and 82%~90% patients will have headaches to varying degrees. At first, it was intermittent, and it became heavier and heavier when waking up in the morning and at night.

2. Vomiting is one of the main symptoms, and about 2/3 patients have vomiting. It is common in severe headache, accompanied by nausea and vomiting. Serious people can't eat, and they will vomit after eating.

3. Optic papilla edema is the most important objective sign of intracranial hypertension. Patients with infratentorial and midline tumors appeared earlier, while supratentorial benign brain tumors appeared later, and some even did not appear. The early stage of nipple edema did not affect vision, and the physiological blind spot of visual field examination expanded.

For many years, Professor Xu has been engaged in the research of brain tumors such as skull base tumors and brain stem tumors, spinal cord tumor's disease and spinal cord diseases, and teaching neurosurgery. He has successively won 8 prizes for scientific and technological progress and educational achievement at the municipal level, a model worker in Shanghai and 100 famous doctors in China.
