Abstract

Arachnoid cysts are congenital cerebral spinal fluid (CSF) collections that most of times are incidentally diagnosed, but can cause symptoms of elevated intracranial pressure. In most cases, middle fossa arachnoid cysts (MFAC) have a benign natural history and remain asymptomatic, requiring only conservative treatment and surveillance. On the other hand, those patients who present or become clearly symptomatic, surgical intervention is mandatory. There are mainly two options of surgical treatment: cystoperitoneal shunt or cyst fenestration either microsurgery or endoscopic.  This article aims to review the clinical presentation of MFAC, discuss the management of symptomatic and asymptomatic patients and review current surgical techniques.
