Sellar Arachnoid Cyst
Sellar arachnoid cysts can be treated with simple endoscopic cyst obliteration – a technique described by our group
Sellar arachnoid cysts are benign fluid-filled masses that can cause loss of pituitary gland function, visual loss & headache.
Arachnoid cysts occurring in the sella and suprasellar region are relatively uncommon. Like arachnoid cysts in other parts of the intracranial space, sellar arachnoid cysts are thought to develop from an arachnoid* pocket or diverticulum that progressively fills with cerebrospinal fluid (CSF).
As these benign cysts enlarge, the can put pressure on the adjacent pituitary gland, optic chiasm and nerves and surrounding skull base membranes, leading to loss of pituitary gland function, visual loll and/or headaches.
Treatment of symptomatic sellar and suprasellar arachnoid cysts is ideally performed through an endoscopic endonasal approach using a simplified cyst obliteration technique with an abdominal fat graft.
This technique was originally described by our group in the Journal of Neurosurgery in 2012 and was shown to have a high success rate and low complication rate.
At Pacific Pituitary Disorders Program, we have one of the world’s largest experiences in transsphenoidal endoscopic endonasal surgery. By incorporating cutting edge technology and instrumentation with proven surgical experience of over 1600 endonasal surgeries, we make arachnoid cyst surgery safer, less invasive and more effective.
*Arachnoid is a thin delicate membrane that surrounds the brain and spinal cord.
