Dear Editor,

The most common presentation of symptomatic brain arteriovenous malformations (AVM) is intracranial hemorrhage [2, 4]. Less common presenting symptoms are epilepsy, headache and focal neurological deficits [4]. Symptoms secondary to hydrocephalus are unusual in adults, and we found only six reports in the literature describing unruptured AVM as the source of hydrocephalus in adults [4, 5, 6, 7, 9].

Obstruction of the ventricles by a drainage vein or the nidus of AVM is the cause of hydrocephalus in unruptured AVM. A less common cause in unruptured AVM is overproduction of cerebrospinal fluid (CSF) [1].

Endoscopic surgery is generally considered advantageous to treat obstructive hydrocephalus due to compression of the Sylvius aqueduct by tumor or aqueductal stenosis. Recent advances in optical technology have allowed new endoscopic surgical options in skull base and pituitary tumors, colloid cysts and arachnoid cysts.

We report two adult patients with unruptured AVM...
