The authors report on three consecutive cases of periaqueductal cysts, causing non-communicating hydrocephalus, successfully treated with endoscopic fenestration and aqueductal stenting. Navigation and cyst fenestration were accomplished using a slim (1.1 mm outside diameter) optic fiberscope inserted via a precoronal-paramedian burr hole. Third ventriculostomy was also performed after cyst fenestration in two cases. Because of the lack of data regarding such lesions and the possible recurrence with simple fenestration, an aqueductal stent connected to a subcutaneous reservoir was placed, in all 3 cases, under direct visualization. Average duration of the procedure was less than sixty minutes and there were no intra- or perioperative complications. All patients recovered clinically and their postoperative neuroirnaging assessment confirmed a decrease in size of both the ventricular system and cyst (mean follow-up: 6.8 months). The authors conclude than this minimally invasive procedure is a promising, safe and effective method to treat cerebral symptomatic periaqueductal cysts and associated non-communicating hydrocephalus.
