Summarycolon;We have reviewed the literature regarding intracranial arteriovenous malformations lpar;AVMsrpar; diagnosed in childhood. Although these lesions seem to be of the same structure and distribution as AVMs first diagnosed in adult life, they have a more malignant course. As many as 87percnt; of patients initially present with hemorrhagesemi; many of these patients progress to coma. Mortality related to the initial bleed is reported to be 25percnt;. The risk of repeat bleed may also exceed the 2hyphen;4percnt; per annum figure usually quoted. However, children who survive the intracranial hemorrhage and receive definitive treatment can do well, despite presenting to the emergency room in extremis. In this article, we review the clinical presentation, natural history, and treatment outcome of arteriovenous malformations presenting before 18 years of age.
