Quistes aracnoideos del sistema nervioso central. Algoritmos y recomendaciones generales de manejo

The symptoms related to the presence of arachnoid cysts in the Central Nervous System depend on the size of the cyst and its growth rate, its location and, in some cases, the associated CSF dynamic disorder. Sometimes there is acute clinical presentation due to cyst rupture or acute bleeding. Although it is generally accepted that asymptomatic or paucisymptomatic cysts do not require surgical treatment, there is no consensus on the therapeutic approach of choice in symptomatic cases. The aim of this paper is to review the literature, analyzing the pros and cons of the three main surgical options (microsurgery, neuroendoscopy, and CSF shunt) based primarily on the location of the cyst. Although treatment must be always individualized, basic management recommendations may be offered.
