Purpose or Case Report: Review the causes of cerebral hemorrhage in the pediatric patient based on clinical cases.

Stroke is a major cause of morbidity and mortality in children worldwide. The reported annual incidence ranges from 2.3 to 13 per 100,000 children per year in developed countries. In contrast to the adult, in children, diagnosis is not as straightforward, because when children present with acute neurological deficits, stroke is often not the first diagnosis considered by the medical providers.

Neuroimaging is essential for diagnosis and differentiation of stroke from stroke mimics that can present similarly.

Stroke in children can be ischemic or hemorrhagic, referring to the term hemorrhagic stroke as a intracerebral hemorrhage that is nontraumatic and whose most common etiology is secondary to a vascular malformation (Arteriovenous Malformation (AVM), Dural/Pial Arteriovenous Fistula (Dural AVF/Pial AVF), Cavernous Malformation, Vein of Galen Aneurysmal Malformation (VGAM), Developmental Venous Anomaly (DVA), Capillary telangiectasia, Sinus Pericranii, Aneurysms).

The most commonly used classification of vascular malformation is based on angioarchitectural and histomorphological characteristics. To differentiate these classic types, in a first step, shunting lesions have to be discerned from nonshunting lesions, as well as other features of the vascular contribution that will be evaluated by image.

We cannot forget the hemorrhage associated with coagulopathy, haematological disorders, brain tumors and cerebral sinovenous thrombosis (CSVT) which in the latter case can be found as venous infarction or hemorrhage; and other less common causes of hemorraghe in pediatrics as the intracranial aneurysms, in 15% of all pediatric aneurysms are secondary to an infection (micotic aneurysm).
