How serious is 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 grow over time?

An arachnoid cyst that causes symptoms needs to be evaluated for possible treatment, as it may continue to grow and cause neurological damage as it puts pressure on surrounding brain tissue.

When large, as in this patient, they can cause a mass effect. A craniotomy for fenestration of the arachnoid cyst was performed; subsequently, a right frontal cyst-peritoneal shunt was placed…

Do arachnoid cysts go away?

The rupture of the cyst wall appears to be essential for the arachnoid cyst to disappear. After rupture, subdural effusion must develop around the cyst. As this effusion is absorbed, the fluid in the cyst drains away, after which the cyst becomes smaller and gradually disappears.
