Quiste aracnoideo espinal pediátrico: a propósito de un caso clínico

An arachnoid cyst is defined as the presence of a collection of cerebrospinal fluid contained in the arachnoid membrane. Its finding in paediatric patients is uncommon. The prevalence is 1-3%, with different aetiologies. There is a predominance of male sex and the location can be intracranial or spinal. These cysts can occur as early as during pregnancy and be asymptomatic or symptomatic. Clinically they cause neurological problems. Detection by imaging tests in a symptomatic patient allows timely surgical treatment. In this article we report the case of a female paediatric patient with an intradural arachnoid cyst in the chest who had preoperative neurological symptoms and followed a post-surgical rehabilitation programme.
