Letter to the Editor of Acta Neurochirurgica: Obstructive hydrocephalus caused by unruptured arteriovenous malformation treated with endoscopic third ventriculostomy.

摘要

The most common presentation of symptomatic brain arterio-venous malformations (AVM) is intracranial hemorrhage [2,4]. Less common presenting symptoms are epilepsy, headache and focal neurological deficits [4]. Symptoms secondary to hydro-cephalus are unusual in adults, and we found only six reports in the literature describing unruptured AVM as the source of hydrocephalus in adults [4-7, 9].Obstruction of the ventricles by a drainage vein or the nidus of AVM is the cause of hydrocephalus in unruptured AVM.
