Arachnoid cysts: diagnosis and treatment
Insights
This study details arachnoid cysts in pediatric patients, finding cranial enlargement and seizures common. Cystoperitoneal shunting combined with ventriculoperitoneal shunting is the recommended treatment for these brain cysts.
Area of Science:
- Neurosurgery
- Pediatric Neurology
- Neuroradiology
Background:
- Arachnoid cysts are congenital, often asymptomatic, fluid-filled sacs.
- Supratentorial and infratentorial arachnoid cysts present unique diagnostic and management challenges in children.
- Pediatric patients with arachnoid cysts may exhibit symptoms like macrocephaly, seizures, and developmental delays.
Purpose of the Study:
- To review clinical presentation, diagnostic imaging, and therapeutic strategies for pediatric arachnoid cysts.
- To evaluate the efficacy of different neuroradiological techniques in diagnosing arachnoid cysts.
- To establish optimal treatment guidelines for pediatric arachnoid cysts based on clinical and imaging findings.
Main Methods:
- Retrospective analysis of 30 pediatric patients (0-15 years) with arachnoid cysts.
- Neuroradiological assessment including CT, metrizamide CT, cisternography, and angiography.
- Echography utilized in 5 neonatal cases.
Main Results:
- Twenty supratentorial and 10 infratentorial cysts were identified.
- Common presenting symptoms included cranial enlargement, epileptic seizures, and psychomotor retardation.
- Combined cystoperitoneal and ventriculoperitoneal shunting demonstrated effectiveness for managing cysts and associated hydrocephalus.
Conclusions:
- Arachnoid cysts in children require a multidisciplinary approach for diagnosis and management.
- Advanced imaging techniques are crucial for accurate localization and characterization of arachnoid cysts.
- Combined shunting procedures represent the preferred surgical intervention for symptomatic pediatric arachnoid cysts and hydrocephalus.
Abstract:
Twenty supratentorial and 10 infratentorial arachnoid cysts are reported. The patients were from 0 to 15 years of age. The commonest presenting symptoms in children were cranial enlargement, epileptic seizures, and psychomotor retardation. Neuroradiological evaluation included CT, metrizamide CT, cisternography, and angiography. Echography was performed in 5 newborns. Therapeutic criteria according to the clinical and neuroradiological findings are reviewed. Cystoperitoneal shunting in combination with ventriculoperitoneal shunting for associated hydrocephalus is considered the treatment of choice.
