Surgical options for suprasellar arachnoid
cyst are cystoperitoneal shunt,
craniotomy fenestration and endoscopic fenestration. Endoscopic management has been found to be safe and effective. We report our experience with endoscopic management in 12 (male five, female seven; age range 8 months to 42 years) patients with suprasellar arachnoid
cyst. The endoscopic procedure included lateral ventricle
puncture by precoronal burr hole and superior and inferior wall of the
cyst was communicated with the lateral ventricle and the interpeduncular cistern respectively. All patients had
hydrocephalus. Four pediatric patients had
macrocephaly. All adult patients had visual disturbances. One adult patient presented with psychomotor disturbance along with features of raised intracranial pressure. All cases improved following endoscopic treatment. There were no complications or death. One patient required VP shunt. Postoperative MRI showed significant reduction in
cyst volume in 11 patients. Follow-up ranged from 6 months to 6 and a half years. Our study suggests that endoscopic technique is a safe and effective alternative treatment for suprasellar arachnoid
cyst. It prevents complications such as
subdural effusion and intracranial
hematoma, which are not uncommon with
craniotomy fenestration.
