BACKGROUND: @entity932 containing cerebrospinal fluid (CSF) may be developmental or acquired. OBJECTIVE: To analyze the results of endoscopic neurosurgery in the management of intracranial CSF cysts. METHODS: In a 7-year period, 64 consecutive @entity1 underwent endoscopic neurosurgery for CSF cysts. Group 1 consisted of 13 @entity1 with acquired cysts; group 2 included 51 @entity1 with @entity245 . In all cases, the cyst walls were fenestrated through small burr holes with frameless guided operative endoscopes. Follow-up ranged from 1 to 6 years (mean, 3.4 years). RESULTS: There were no mortality and no permanent morbidity, apart from a @entity1 (1.6%) who remained neurologically intact but required ventriculoperitoneal shunting because of @entity548 . The planned fenestrations could be performed in all @entity1 except 2, owing to thick, opaque cyst walls. In group 1, 6 @entity1 fully recovered and remained intact throughout the follow-up, whereas 7 improved but had various degrees of @entity16 that were related to their initial diseases. Radiological results were excellent in all cases. In group 2, there were 7 asymptomatic @entity1 who remained unchanged and 44 "symptomatic" @entity1 : 40 (91%) clinically improved, 4 (9%) remained unchanged, and none worsened. Cyst size decreased in 37 @entity1 (74%) and remained unchanged in 13 (26%). CONCLUSION: In this series, @entity1 of different ages, harboring cysts of various sizes and locations, could be satisfactorily treated with endoscopic neurosurgery.
