Arachnoid cyst causing obstructive hydrocephalus
Luis Izquierdo, MD
This is a case of arachnoid cyst, towards the base of the skull at the level of the circle of Willis.
It seemed that the posterior cerebral and the posterior communicating vessels are displaced. The power Doppler shows circulation to middle cerebral artery and anterior vessels.
A repeat examination 3 weeks later demonstrated obstructive hydrocephalus as a complication.
