Understanding intracranial arachnoid cysts: a review of etiology, pathogenesis, and epidemiology

Area of Science:

• Pediatric Neurosurgery
• Neurology
• Developmental Neuroscience

Background:

• Arachnoid cysts (AC) are frequently diagnosed in pediatric neurosurgical cases.
• Increased diagnostic imaging availability leads to more frequent incidental findings.
• Accurate incidence and prevalence data for arachnoid cysts remain undetermined.

Purpose of the Study:

• To review current knowledge on arachnoid cysts (AC).
• Focus on etiology, pathogenesis, and epidemiology.
• Highlight location-specific findings, such as Sylvian fissure cysts.

Main Methods:

• Literature review of arachnoid cyst research.
• Synthesis of data on etiology and pathogenesis.
• Epidemiological analysis and discussion of diagnostic trends.

Main Results:

• Arachnoid cysts are common pediatric neurosurgical pathologies.
• Incidental detection is increasing due to advanced imaging.
• Debate continues regarding optimal symptomatology, treatment indications, and modalities.
• Etiology, pathogenesis, and epidemiology are discussed, with emphasis on Sylvian fissure locations.

Conclusions:

• Arachnoid cysts require further research for definitive incidence and prevalence.
• Standardized approaches to symptomatology and treatment are needed.
• Understanding specific locations like the Sylvian fissure is crucial for management.
