Surgical Treatment of Arachnoid Cyst
There are several ways to surgically treat arachnoid cysts. The aim of surgery is to release the cyst and localized pressure on the surrounding brain and structures and to reconstitute normal CSF flow.
Operation
. Marsupialisation of Arachnoid Cyst
The patient will be given a general anaesthetic and an incision made overlying the region of the arachnoid cyst. A craniotomy is then performed to expose the arachnoid cyst.
Once this is done the cyst is incised under direct vision. The walls of the cyst are removed where possible and laid open to allow free flow of cyst fluid with the surround CSF.
The bone is then replaced and secured with titanium plates. The skin is then closed with staples or stitches.

. Fenestration of Arachnoid Cyst
If it is not possible to fully lay open the arachnoid cyst wall, the wall may be fenestrated to allow communication of the cystic cavity with the surrounding CSF. This is often done in the deep cisterns of the CSF spaces of the brain. An endoscopic approach may be taken rather than a craniotomy for this approach.
. Shunting of Arachnoid Cyst
For recurrent arachnoid cysts a cysto-peritoneal shunt may be require to definitively treat the cyst. This allows flow of cyst fluid from the cyst into the abdominal cavity, thereby relieving decompressing the cyst and relieving pressure on the surrounding structures.
Surgical treatment of arachnoid cysts are generally well tolerated. Occasionally a second operation may be required, particularly if there is scarring at the previous operation site resulting in reformation of the cyst.

Can you die from an arachnoid cyst?
None of the children died or had major disability. As more children with arachnoid cysts are identified, neurosurgeons need the best possible information on risk factors for rupture or bleeding. The risk that an arachnoid cyst will rupture or bleed has been estimated somewhere between two and five percent
Is arachnoid cyst life threatening?
Are Arachnoid Cysts Life-Threatening? Arachnoid cysts are benign fluid-filled sacs that form between the arachnoid membrane and the central nervous system. … The most severe form of presentation can lead to bleeding (hemorrhage), damage to the central nervous system and sometimes even death.
What is the treatment for arachnoid cyst?
Surgery for arachnoid cysts is generally safe, with good outcomes. There are three surgical options for treating an arachnoid cyst: A pediatric neurosurgeon may place a permanent drainage system, a type of shunt, to drain fluid from the cyst and reduce pressure on the brain.
Can arachnoid cysts grow?
Primary, or congenital, arachnoid cysts are usually caused by an abnormal growth of your brain and spinal column while you’re developing in utero. The exact cause of this growth is not known. It might be genetic. Secondary arachnoid cysts, also known as noncongenital arachnoid cysts, can be caused by several things
What can happen if a cyst is left untreated?
If left untreated, benign cysts can cause serious complications including: Infection – the cyst fills with bacteria and pus, and becomes an abscess. If the abscess bursts inside the body, there is a risk of blood poisoning (septicaemia).
Do arachnoid cysts go away?
Symptoms usually resolve or improve with treatment. Untreated, arachnoid cysts may cause permanent severe neurological damage when progressive expansion of the cyst(s) or bleeding into the cyst injures the brain or spinal cord. Symptoms usually resolve or improve with treatment.
How serious is an arachnoid cyst?
Untreated, arachnoid cysts may cause permanent severe neurological damage when progressive expansion of the cyst(s) or bleeding into the cyst injures the brain or spinal cord. Symptoms usually resolve or improve with treatment
Do arachnoid cysts require surgery?
Most arachnoid cysts are stable and do not require treatment. … Arachnoid cysts are diagnosed with a CT or MRI scan. Treatment, if necessary, involves draining the fluid through surgery or shunting.
Can an arachnoid cyst cause personality changes?
Neurological signs may be present because arachnoid cysts may cause increased pressure on structures of the brain. Such neurological findings may include developmental delays, behavioral changes, an inability to control voluntary movements (ataxia), difficulties with balance and walking and cognitive impairment.
Can an arachnoid cyst turn into cancer?
Brain cysts are fluid-filled sacs that may form in the brain. They can be benign (not cancer) or malignant (cancer). … These include arachnoid, colloid, dermoid, epidermoid, pineal, infectious, and tumor cysts. Even when brain cysts are noncancerous, they may press against brain tissue and cause symptoms
