Microsurgical treatment of a large posterior fossa arachnoid cyst
Keywords:microneurosurgery, arachnoid cyst, posterior fossa, fourth ventricle
Introduction: Arachnoid cysts are fluid-filled malformations of the arachnoid tissue. A prevalence in children of 2,6% has been reported[2,3]. Surgical strategies of treatment include open surgery with cyst wall excision , endoscopic fenestration or cystoperitoneal shunting[1,4]. Methods: In this video case, we described the case of a 1 year and 7 months old child who presented with motor development delay, unable to walk, who underwent microsurgical resection of a large posterior fossa arachnoid cyst and communication with the fourth ventricle. Conclusion: Microsurgery approach provides a safe anatomic control over the cyst and the recognition of floor of the fourth ventricle.
