Unruptured Aneurysm Basics

Most aneurysms are quite small and cause no symptoms unless they rupture. Many unruptured aneurysms are found incidentally when tests are being done to screen for other conditions.

Rarely, unruptured aneurysms may become large and press on nerves in the brain, causing symptoms such as blurred or double vision, a drooping eyelid, a dilated pupil, weakness and/or numbness, or pain above and behind the eye. If you experience these symptoms seek prompt medical attention. Unruptured aneurysms rarely cause chronic headaches.

Unruptured aneurysms can also be discovered at the time a ruptured aneurysm is diagnosed. This is not uncommon, as one in five people diagnosed with an aneurysm has more than one.
