Familial posterior fossa arachnoid cyst.
BACKGROUND
Arachnoid cysts are a relatively common incidental finding on CT scans of the brain. They most commonly occur in the middle cranial fossa, where familial occurrence has rarely been reported. Posterior fossa arachnoid cysts are more unusual.


METHODS
We report the presence of quadrigeminal cistern arachnoid cysts in siblings.
