What is it about?
Commonly and traditionally large sylvian arachnoid cysts (Galassi type III) were operated on even the clinical symptoms and signs were absent or mild. Because of the mass effects of the cysts and the lack of normal brain parenchyma experienced cases with conservative management and found that surgery may not be indicated if evidence of increased intracranial pressure (ICP) such as obstructive hydrocephalus or papilledema is absent. Especially when performed in young age, surgery is associated with complications, another concern.

Why is it important?
The decision on surgery in large sylvian arachnoid cysts should be made more carefully considering its natural course.
Perspectives
The authors expect that further accumulation of non-surgical cases will reveal natural history of large sylvian arachnoid cyst more clearly.
