Aneurysms are usually clinically silent and diagnosed incidentally or when they cause complications such as compression of adjacent structures, bleeding or rupture. Large aortic aneurysms can cause deep, diffuse chest pain, or rarely, difficulty in swallowing or hoarseness. Aneurysms in the brain may cause symptoms of headache.
Rupture of aneurysms of the aorta or brain are usually fatal, due to severe shock caused by massive leakage of blood into the chest or abdomen and major stroke caused by haemorrhage in the brain, respectively.
Detecting an aneurysm early may be difficult due to the initial lack of symptoms. Aneurysms are usually clinically silent and diagnosed incidentally or when they rupture. At a later stage, symptoms usually depend on the size and location of the aneurysm.
