Arteriovenous malformations (AVMs) of the posterior fossa are complex neurovascular lesions that are less common than their supratentorial counterparts, accounting for < 15% of all AVMs. The majority of patients with these lesions present with intracranial hemorrhage, a factor that has been consistently shown to increase one's risk for subsequent bleeding. Studies have additionally shown a posterior fossa or deep AVM location to portend a more aggressive natural history. The authors reviewed the literature on posterior fossa AVMs, finding their annual rupture rates to be as high as 11.6%, an important factor that underscores the importance of aggressive treatment of lesions amenable to intervention as therapeutic options and results continue to improve.

“…There is a high propensity (80%) for the AVM childhood to present bleeding 8 , what is higher than that reported for adults 9,[15][16][17] . Likewise, epilepsy was reported in 12-18%of the AVM` s children series 7,18 and in 16 to 53% of the adult patients 19,20 .…”

-Headache as a chief complaint is rare in the paediatric emergency room.Actually, very seldom cases secondary to life threatening conditions as non-traumatic subarachnoid haemorrhage have been reported. A child with severe headache and nuchal rigidity and no other abnormalities on the physical examination is reported. Magnetic resonance angiography and cerebral angiography disclosed a ventricular arteriovenous malformation in the choroid plexus, supplied by the anterior choroidal artery, classified according to Spetzler grading system as grade 3 (deep venous drainage: 1; eloquence area: 0 and size: 2).The differences in the clinical presentations of the central nervous system arteriovenous malformation between children and adults are discussed.KEY WORDS: secondary headache in children, arteriovenous malformation of the brain, pediatric stroke. Hemorragia cerebral secundária a malformação artério-venosa ventricular: uma causa rara de cefaléia na infân-cia. Relato de casoRESUMO -Cefaléia como queixa principal raramente ocorre num serviço de emergência pediátrica. Quando isso acontece, casos de cefaléia secundária que trazem risco de vida, tais como a hemorragia subaracnóide são raramente relatados. Apresentamos o caso de uma criança que apresentou cefaléia de forte intensidade associada a rigidez de nuca, sem outras anormalidades no exame físico. A angioressonância e angiografia digital evidenciaram malformação arteriovenosa na topografia do plexo coróide do ventrículo lateral direito, nutrida pela artéria coroidéia anterior, grau III na classificação de Spetzler (drenagem venosa profunda: 1; área de eloqüência: 0 e tamanho: 2). Nós discutimos as diferenças na apresentação clínica das malformações arteriovenosas encefálicas nas crianças e adultos. PALAVRAS-CHAVE: cefaléia secundária, malformação arteriovenosa do encéfalo, malformação arteriovenosa ventricular.A headache due to a hemorrhagic stroke is a life-threatening clinical condition rarely seen in a paediatric emergency department 1,2 .When it occurs, an arteriovenous malformation should be ruled out. The arteriovenous malformation of the brain (AVM) accounts for 30% to 50% of such hemorrhagic strokes in children [3][4][5][6] and it has been associated with a 25% mortality rate 7 . On the other hand, the ventricular location is found in only 4% of the AVM in childhood 8 ; and in 1,3% of the adult's AVM 9 . We report a child with a history of sudden headache secondary to a bleeding of a ventricular arteriovenous malformation. CASEA 9-year-old previously healthy girl was admitted to the Emergency Room with an eight-hour history of sudden onset of severe headache. The pain was pulsatile and bilateral and not accompanied by other symptoms. There is no history of migraine, epilepsy or stroke. Parents reported that soon after the onset of the headache the patient

“…Various factors have been proposed to playa role in the pathogenesis of spontaneous resolution of AVMs. These include haemorrhagic presentation with haematoma compression of the nidus of AVM or lesional thrombosis [5].…”
