Intracranial vascular malformations are the most common cause of spontaneous intracranial hemorrhage in childhood and are congenital abnormalities of central nervous system development. The reported incidence varies among statistics and is approximately 1 in 1,000 to 40 in 1,000. There are four types of intracranial vascular malformations: 1) arteriovenous malformations (AVM); 2) cavernous hemangiomas; 3) capillary dilation; and 4) venous malformations. AVMs have a high incidence in childhood, often with intracranial hemorrhage as the first symptom, some patients have seizures, headache, hemiparesis, and aphasia. Large venous tumors of the brain in children can lead to heart failure and hydrocephalus. Spongiform hemangioma: Some children are hereditary and can be solitary, while about 20% of children have multiple intracranial lesions. There are no large blood supplying arteries or draining meridians, and small amounts of bleeding can recur. Seizures are the most common first symptom, followed by cerebral hemorrhage. Meridional malformation: often manifested by epilepsy, bleeding is less common. Capillary vasodilatation: rare. It is often asymptomatic and can partially cause pontocerebral hemorrhage. Craniofacial hemangiomatosis: Sturge-Weber syndrome, which is an arteriovenous and capillary malformation of the meninges on the same side of the facial hemangioma. It is often associated with mental retardation and epilepsy.
