“…17 Many theories have been offered to explain the pathogenesis of arachnoid cysts, including inciting events such as infection, trauma, and metabolic alterations. 17,22 It has been postulated that arachnoid cysts primarily result from duplication and splitting of the arachnoid endomeninx, which normally develops into the pia and arachnoid layers as well as the subarachnoid space. 22 The potential expansion of arachnoid cysts during subsequent development likely has multifactorial causes.…”

Object Arachnoid cysts can cause a variety of clinical signs and symptoms in infants. The authors sought to determine whether the clinical presentation of pediatric patients younger than 2 years old and harboring arachnoid cysts influenced the type of intervention that would be required. Methods A retrospective chart review was conducted for all patients younger than 2 years of age who had undergone craniotomy for fenestration of an arachnoid cyst at the Childrens Hospital Los Angeles between 1995 and 2006. Forty-two patients were included in the study. The mean age was 10.4 months. The median follow-up time was 33 months. Clinical presentations were as follows: macrocephaly without ventriculomegaly (21 patients, 50%), hydrocephalus (six patients, 14%), and other symptoms (15 patients, 36%). After fenestration of the arachnoid cyst, 12 of 21 patients (57%) presenting with nonspecific macrocephaly required placement of a cystoperitoneal or ventriculoperitoneal shunt, compared with 1 of 15 patients (7%) presenting with other symptoms (p value = 0.0039). Five of six patients with hydrocephalus (83%) were shunt dependent following fenestration. Overall, 18 of 42 patients (43%) were shunt dependent after fenestration. Ten of these patients (55%) required revisions during the follow-up period. Conclusions Patients younger than 2 years of age and harboring an arachnoid cyst commonly present with macrocephaly. These patients are more likely to require shunts than are those presenting with other findings, such as seizu

“…9 In any case, progressive growth of arachnoid cysts may cause secondary regional effects such as hypoplasia of the temporal lobe as well as manifest as symptoms such as seizures, developmental delay, visual loss, or motor deficits. 6,7,22,29 Patients with arachnoid cysts may also present with hemorrhagic events, especially following head trauma. 1,19,20,23 Younger patients (Ͻ 2 years of age) are more likely to present with nonspecific macrocephaly than other symptoms or signs.…”

“…Arachnoid cysts are congenital, typically asymptomatic cystic collections of cerebrospinal fluid within the subarachnoid space first described by Bright in 1831 [73,74]. They account for 1 % of all non-traumatic intracranial mass lesions, usually arising within and expanding the margins of CSF cisterns rich in arachnoid [75,76].…”

Ventricular endoscopy in the pediatric population: review of indications

Introduction Neuroendoscopy has greatly impacted pediatric neurosurgery over the past few decades. Improved optics and microsurgical tools have allowed neuroendoscopes to be used for a multitude of neurosurgical procedures. Discussion In this review article, we present the breadth of intraventricular neuroendoscopic procedures for the treatment of conditions ranging from hydrocephalus and brain tumors to congenital cysts and other pathologies. We critically discuss treatment indications and reported success rates for neuroendoscopic procedures. We also present novel approaches, technical nuances, and variations from recently published literature and as practiced in the authors' institution.
