As the epithelial lining continues to produce the soft white keratin material, the cyst puts pressure on the adjacent brain structures and cranial nerves.

This cyst expansion can lead to:

  • Headaches
  • Weakness
  • Imbalance
  • Visual loss
  • Double vision
  • Seizures depending upon the cyst location

Some epidermoid cysts can rupture and result in a meningitis-type reaction from inflammation.


What do I do if I have these symptoms?

These cystic tumors are typically diagnosed by magnetic resonance imaging (MRI) or computer tomography (CT) scans of the brain.

Depending upon the location of an epidermoid cyst, a focused MRI of the pituitary region or internal auditory canals may be indicated to obtain better anatomical detail.


Chemotherapy and radiotherapy are generally not used for treating epidermoid cysts.

Epidermoid Cysts Removal

Epidermoid cyst surgery is required to remove large epidermoid tumors causing symptoms and is generally quite successful in resolving symptoms.

Because the cyst lining can be very adherent to the brain structures, cranial nerves and blood vessels, a complete cyst removal may not be possible in many patients. If only a subtotal removal is accomplished, follow-up MRIs are necessary for many years to monitor for recurrence.
