Anterior cerebral artery aneurysm associated with multiple intracranial aneurysms and abdominal aorta aneurysm

Abstract

We found multiple aneurysms in the intracranial arteries and abdominal aorta of an 87-year-old Korean female cadaver, whose cause of death was reported as "cholangiocarcinoma." An abdominal aortic aneurysm was observed in the infrarenal aorta, where the inferior mesenteric artery arose. The intracranial aneurysms were found in the A3 segment of the anterior cerebral artery and at the bifurcation of the middle cerebral artery. This case provides an example of the very rare association of peripheral intracranial aneurysms with an abdominal aortic aneurysm. Clinicians as well as anatomists should recognize the potential association between these two aneurysm types.

“…Although the general consensus in the scientific community that the main cause for the IA creation, is the weakening of the arterial wall [3,4], the biological, physiological and biomechanical features behind that wall weakening are still unknown [5]. Nevertheless, it is recognized that the more probable causes for this phenomenon, are mainly the acquired lesions caused by congenital defects, atherosclerotic changes, trauma or infectious emboli [3,6,7,4]. It is also notice that persons with some risk factors (such as hypertension, smoking and heavy alcohol consumption, increasing age, female sex and familiar occurrence) are more likely to develop IAs [3,2].…”
