Intraventricular Tumors & Lesions

Intraventricular tumors are a type of brain tumor. They affect the ventricles, which contain a clear liquid called cerebrospinal fluid (CSF) that supports and cushions the brain. Intraventricular tumors are usually benign and grow slowly. If a tumor grows large enough, however, fluid can build up in the brain (obstructive hydrocephalus). Types of intraventricular tumors include central neurocytomas, choroid plexus tumors, colloid cysts, malignant meningiomas, subependymal giant cell astrocytomas (SEGA), and subependymomas.



Symptoms may include:

  • Changes in personality or behavior
  • Confusion
  • Trouble speaking
  • Headaches
  • Weakness or loss of feeling on one side


First, you’ll meet with your doctor for a physical exam. You’ll talk about your symptoms and your doctor may order imaging tests, such as an MRI or a CT scan. After that, your doctor may perform a biopsy of the tumor.

If you’re diagnosed with an intraventricular tumor, your Aurora care team, including neurologists and neurosurgeons from the Aurora Neuroscience Innovation Institute, will work with you to develop a treatment plan to fit your needs.

Treatment Options

Dr. Amin Kassam, vice president for Neurosciences at Aurora Health Care, explains the Expanded Endonasal Approach, a minimally invasive surgery technique.

Treatments may include:

  • A shunt (a tube implanted to drain fluid in the brain)
  • Radiation therapy
  • The Expanded Endonasal Approach (EEA), a minimally invasive procedure in which the tumor is removed through the nasal passages, resulting in no incisions, a shorter hospital stay and faster recovery.
