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

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.
