Anterior cerebral artery aneurysm associated with multiple intracranial aneurysms and abdominal aorta aneurysm
During a routine dissection at Jeju National University Medical School in 2012, multiple aneurysms were observed in the intracranial arteries and abdominal aorta of an 87-year-old female Korean cadaver, whose cause of death was listed as "cholangiocarcinoma." The protocol for the current report did not include any specific issue that required the approval of the ethics committee of our institution, and it conformed to the provisions of the Declaration of Helsinki in 1995.\nGross dissection was performed in the customary fashion. During dissection, an aneurysm was observed in the infrarenal aorta, 19.1 mm superior to its bifurcation into the common iliac arteries. The size of the AAA was 46.5×40.6×36.7 mm where the inferior mesenteric artery arose (). In longitudinal section, atherosclerotic thickening was observed.\nAfter removal of the brain, we found multiple aneurysms in the intracranial arteries (); one aneurysm was located in the A3 segment of the ACA and another at the bifurcation of the MCA. A distal ACA aneurysm was located on the central part of the A3 segment, anterior to the genu of corpus callosum, 18.0 mm distal to the anterior communicating artery. The aneurysm was a small berry-type aneurysm, with a size of 6.8×5.5×3.7 mm. The aneurysm at the bifurcation of the MCA was located 13.5 mm distal to the bifurcation of the internal carotid artery (ICA) into the ACA and MCA. The aneurysm was a small saccular-type aneurysm with a size of 4.3×2.8×3.2 mm.
