Do symptoms like cavernous sinus aneurysm go away quickly?

Not usually: Aneurysms of the cavernous sinus may cause symptoms from compression of the nerves which control eye movement, or compression of the nerves which supply sensation of the face. Once these symptoms occur, they are unlikely to go away without treatment of the aneurysm. These aneurysms are unlikely to resolve on their own. If it is causing symptoms, it probably should be treated.
