Increased intracranial pressure is not necessarily a brain tumor, but can also be seen in craniocerebral trauma, intracranial infection, cerebrovascular disease and other conditions. 1. Brain tumor is only one of the causes of increased intracranial pressure. In addition to the symptoms of increased intracranial pressure, patients with brain tumor may also have symptoms of neurological damage, such as hemiparesis, aphasia, sensory impairment or even coma. 2. Craniocerebral trauma Intracranial hematoma due to intracranial blood vessel injury, cerebral contusion with cerebral edema are common causes of traumatic intracranial pressure increase. 3. Intracranial infections, such as pyogenic meningitis or brain abscess, can also cause increased intracranial pressure. 4. Cerebrovascular disease Cerebral hemorrhage caused by various reasons can cause obvious increase in intracranial pressure, such as intracranial aneurysm rupture bleeding, cerebral vascular malformation bleeding and so on. If there are signs and symptoms of high intracranial pressure, such as headache, nausea, vomiting, optic papillae edema, etc., you should go to the hospital in time to look for the cause of the disease and get treatment under the guidance of the doctor.
