About Epidermoid Tumor (Cyst)

General Information

  • Normally benign, these slow-growing tumors can occur in various structures of the skull, spine and brain when normal developmental cells are trapped within the growing brain.


  • Depending on the location of the tumor, symptoms can include vision difficulties, seizures, fever, headaches, neck stiffness, facial pain, numbness, or weakness and hearing loss.


  • Both magnetic resonance imaging (MRI) and computed tomography (CT) brain scans can identify these tumors.


  • Surgery is the primary treatment. Use of the endoscope may be very helpful in obtaining a more complete surgical removal.


  • Almost 100 percent of scalp and skull epidermoids and 50 percent to 80 percent of intracranial and intraspinal cysts can be removed completely.
  • An incomplete removal generally means that only a tiny remnant of the cyst lining was left behind.
  • Clinical recurrence is infrequent even when small fragments of cyst lining are left behind.
  • Occasional operative complications result from damage to nerves, blood vessels, or brain or spinal cord.

The Neuro-ICU cares for patients with all types of neurosurgical and neurological injuries, including stroke, brain hemorrhage, trauma and tumors.

Together with the surgeon or medical doctor, the Neuro-ICU attending physician and team members direct your family member's care while in the ICU.
