You can feel confident in relying on the expertise of the brain aneurysm specialists at Johns Hopkins, as Les Picker did when he was facing an aneuryism:

Ophthalmic Nerve Aneurysm | Les Picker's Story

Lester Picker is lucky to be alive and he knows it. Diagnosed with an aneurysm on his ophthalmic nerve, Dr. Raphael Tamargo, from Johns Hopkins Department of Neurosurgery clipped his aneurysm, preventing it from rupturing.

What is an unruptured brain aneurysm?

Unruptured brain aneurysms

An aneurysm is a bulging, weakened area in the wall of an artery, resulting in an abnormal widening or ballooning. Because there is a weakened spot in the artery wall, there is a risk for rupture (bursting) of the aneurysm. An unruptured aneurysm, therefore, is an aneurysm that has not yet ruptured.

The presence of an aneurysm may not be known until too late when it ruptures. However, occasionally there may be symptoms that occur before an actual rupture rapid expansion of the aneurysm in the final stages before it ruptures.


Symptoms of an Unruptured Brain Aneurysm

The symptoms of an unruptured aneurysm include, but are not limited to, the following:

  • headaches
  • dizziness
  • eye pain
  • vision deficits (problems with seeing)
  • double or blurry vision
  • seizures

The symptoms of an aneurysm may resemble other problems or medical conditions. Always consult your physician for a diagnosis.

Diagnosis of an Unruptured Brain Aneurysm

Most unruptured aneurysms are discovered incidentally during routine imaging of the brain, such as an MRI or CT scan (see Diagnosis of a Brain Aneurysm). A person with a family history of brain aneurysms would be encouraged to have screening performed, at which point an unruptured aneurysm might be found. Additionally, some persons might be prompted to have imaging performed due to the onset of other neurological symptoms, such as headaches or visual disturbances.

Many unruptured brain aneurysms are found due to neurological symptoms caused by the size of the aneurysm. Some aneurysms are quite large in size and may push on a nerve in the brain, causing what is called the "mass effect." The aneurysm may cause neurological symptoms such as blurring of vision, headaches, and more, before bleeding.

Treatment for an Unruptured Brain Aneurysm

Specific treatment will be determined by your physician based on:

  • your age, overall health, and medical history
  • extent of the disease
  • your signs and symptoms
  • your tolerance of specific medications, procedures, or therapies
  • expectations for the course of the disease
  • your opinion or preference
