Patients with cerebral hemangiomas have no obvious symptoms in daily life, but if they rupture and bleed, they are more likely to be life-threatening and belong to the serious category of diseases. Cerebral hemangioma, also known as intracranial aneurysm, is a cystic protrusion in the wall of an intracranial artery that can easily rupture and bleed when blood pressure rises and emotions are excited. When a cerebral hemangioma ruptures, the patient may have severe headache, frequent vomiting, and may suffer from impaired consciousness or even coma, as well as hemiplegia and aphasia. If the amount of bleeding is large and affects brainstem function, respiratory and cardiac arrest may occur and endanger life. However, if the patient’s blood pressure and blood lipids are well controlled and the size of cerebral hemangioma is small, in most cases there are no obvious symptoms and it is not life-threatening. If the cerebral hemangioma does not have any symptoms, conservative treatment can be adopted. However, if the patient’s own condition allows, interventional and minimally invasive treatment should be performed in time.
