Dis(appearance) of an Arachnoid Cyst: A Follow-up Imaging Perspective

Arachnoid cysts (ACs) are cerebrospinal fluid (CSF) –filled sacs that are responsible for 1% of all intracranial lesions. (1)(2) Although the etiology remains unknown, expert consensus suggests that ACs are developmental anomalies/congenital malformations. Patients with a diagnosis of AC are typically asymptomatic, even if the cyst increases in size. (2) There is no consensus about the ideal age to repeat imaging and how long to radiographically monitor asymptomatic children who have an AC.
