Chronic subdural haematoma after endoscopic treatment of a supracellar arachnoid cyst.

ABSTRACT

Neuroendoscopy is considered a safe treatment option for intracranial arachnoid cysts. However a variety of complications has been reported after such interventions. Here we present the first case of a chronic subdural hematoma two months after the combined treatment of a supracellar arachnoid cyst with endoscopic third ventriculostomy and cyst fenestration.
