Gli autori descrivono 15 casi di cisti aracnoidee operate con tecnica endoscopica. Si tratta di 10 maschi e 5 femmine di età compresa fra 2 mesi e 80 anni con le seguenti localizzazioni cistiche: 6 della valle silviana, 2 soprasellari, 5 in fossa cranica posteriore, 1 della convessità frontale e 1 parietale interemisferica.
I risultati sono stati soddisfacenti con risoluzione dei sintomi clinici in 11 casi (73%) mentre sul piano radiologico una riduzione di volume della cisti si è ottenuta in 7 casi (46%). Vengono discussi vantaggi e limiti della tecnica endoscopica e le indicazioni in riferimento alla localizzazione cistica ed in confronto ai trattamenti tradizionali (craniotomia e shunt).
