Phenomenon of subdural accumulations in children with arachnoid cysts of the Sylvian fissure

Microsurgery with creation of communication between subdural cavity, cyst and basal cisterns is preferable for spontaneous rupture of arachnoid cysts of the Sylvian fissure and tense subdural accumulations in children. Isolated drainage of subdural accumulations may be sufficient in some cases. Clinically not significant subdural CSF collections after endoscopic fenestration of Sylvian fissure arachnoid cysts in children are often and do not require surgical correction in the majority of cases.
