Congenital cerebral hemangiomas are a group of disorders collectively referred to by the general public in non-medical specialties and may include vascular malformations of the brain. Vascular malformations of the brain can be clinically categorized into eight types, so the issue is relatively broad. Cerebral hemangiomas are more specifically malformations of the blood vessels of the brain, some of which may be very serious and some of which are not, such as venous malformations, which may be present in some patients throughout their lives, but can be detected by magnetic resonance imaging (MRI) or angiography, but the patient has no sensation of the disease and the condition is not relatively serious. Some congenital hemangiomas, such as arteriovenous malformations, may also have no symptoms, but if they rupture and bleed, they may cause the patient to be unconscious, or even stop breathing or even die soon, which is the most serious situation. Therefore, cerebral hemangioma should not be considered as very serious or very mild, and should be judged according to the condition.
