Background: The clinicoradiological outcome of endoscopic fenestration of intracranial cysts and predictors of an unfavorable outcome, including age, are under reported in the neurosurgical literature. In this cohort, our experience in the endoscopic fenestration of intracranial cysts is reviewed. Materials and Methods: Thirty consecutive patients treated with endoscopic fenestration for intracranial cysts were identified and analyzed. The study population in our series was followed clinically and radiographically. Results: In this series, the overall resolution of clinical symptoms such as headache, seizures, and neurological deficits was 83%, P= 0.0001. The percentage of clinical resolution after endoscopic intervention was significantly higher (85% vs. 76%, P= 0.001) in arachnoid cysts compared to other cyst types. The reduction of arachnoid cyst size was significantly higher in adults with obstructive hydrocephalus compared to the children group (P = 0.037). In addition, requirement of a cystoperitoneal shunt placement (P = 0.0001) and its subsequent revision (P = 0.0001) was significantly lower in adults compared to children. Adults (P = 0.041), presence of an arachnoid cyst (P = 0.026), female gender (P = 0.016), and presence of communicative hydrocephalus (P = 0.015) were significant predictors for improvement in the symptoms of intracranial pressure. Lastly, adults (P = 0.028), presence of arachnoid cyst (P = 0.046), and presence of communicative hydrocephalus (P = 0.012) were significant positive predictors for shunt revision. Conclusions: This study revealed that endoscopic fenestration is an effective neurosurgical procedure for the management of intracranial cysts both in adults and children. Moreover, endoscopic fenestration is more beneficial in adults and patients with an arachnoid cyst compared to that in children and other cyst types, respectively.
