Unruptured Brain (Cerebral) Aneurysm

An unruptured brain aneurysm, also called a cerebral aneurysm is an aneurysm that has not yet ruptured. Not all brain aneurysms rupture. Using non-invasive imaging methods such as MRIs and MRAs, doctors are now able to detect unruptured brain aneurysms with increased frequency. An unruptured brain aneurysm may or may not cause symptoms. In almost all cases ruptured aneurysms require urgent medical treatment. Unruptured aneurysms, however, may or may not require treatment. In some cases, doctors may recommend follow-up with serial imaging studies. Some of the things doctors consider in whether or not to treat an unruptured aneurysm are:

  • Age and health of patient
  • Family history — is there a family history of unruptured brain aneurysms, and have any of those aneurysms ruptured?
  • Patient preference
  • Risk of hemorrhage — what is the probability that the aneurysm will rupture?
  • Size and location
  • Surgical and endovascular risks

Unruptured Brain Aneurysm Symptoms

Unruptured brain aneurysm symptoms may include but are not limited to the following:

  • Dizziness
  • Double or blurry vision
  • Eye pain
  • Headaches
  • Problems seeing (vision deficits)
  • Seizures
