Symptoms of cerebral hemangioma
- Headache: increased intracranial pressure or tumor direct compression stimulation of meninges, blood vessels and nerves caused by stimulation. In most patients, it is the symptom of early cerebral hemangioma, which is aggravated with the development of tumor.
- Visual impairment: including changes of vision, visual field and fundus. Due to the increase of intracranial pressure, optic nerve papilledema or tumor directly oppresses the optic nerve. Over time, optic nerve atrophy can affect vision, resulting in vision loss or even blindness.
The causes of optic nerve papilledema are the increase of intracranial pressure, the restriction of lymphatic return around optic nerve, the increase of ophthalmic venous pressure and blood stasis. In addition, there are also dizziness, diplopia, mental symptoms, seizures, neck rigidity, corneal reflex, breathing and blood pressure and other vital signs changes.
- Vomit: because intracranial pressure increases, stimulate medullary vomiting center, vagus nerve to be stimulated and pulled to cause more. When the headache is serious, it is complicated with vomiting, often in the form of jet. Vomiting occurs earlier and frequently in children with posterior fossa tumors, which is also a typical symptom of cerebral hemangioma, but it is often mistaken for gastrointestinal disease.
