Patient Data

Age: 41 Years
Gender: Female

There is a well-circumscribed, rounded lesion with imperceptible walls located at the level of quadrigeminal cistern following CSF signal in all pulse sequences without evidence of soft tissue component. It is exerting mass effect over the third ventricle and aqueduct of sylvius with resultant moderate dilatation of the third and lateral ventricles. 

Case Discussion

Quadrigeminal arachnoid cysts are uncommon. Infratentorial arachnoid cysts are more frequently symptomatic comparing to the supratentorial arachnoid cysts. The symptoms occur when the cysts gradually enlarge and causing mass effect over the aqueduct of sylvius and resulting in obstructive hydrocephalus.
