[[Supratentorial]] [[arachnoid cyst]]s are usually [[asymptomatic]] and may be discovered by chance at [[autopsy]]; however, [[infratentorial arachnoid cyst]]s, which correspond to liquid forms enclosed by an [[arachnoid sheet]] but whose [[pathogenesis]] is unknown, might cause [[symptom]]s. They don't need to be treated if they're asymptomatic and were discovered by chance. A variety of neurological symptoms can be present depending on their localization. [[Intracranial dermoid cyst]]s are uncommon tumours that develop from ectopic [[epithelial cell]]s in the [[brain.]] They are benign, slow-growing, and rarely rupture.
