Cerebral aneurysms with eccentric features associated with intrinsic vessel wall deformities A 55-year old woman was admitted because of an aneurysmal subarachnoid hemorrhage (SAH) in the right sylvian fissure (A). A large aneurysm in the right middle cerebral artery (MCA) was considered as a culprit lesion of SAH (B). However, multiple, large aneurysms were also noted in the anterior communicating and anterior cerebral arteries (C), and basilar artery (D). The second patient was a 53-year old woman complaining of anterior chest discomfort. Computed tomography angiography showed a large aneurysm involving the descending thoracic aorta (E, F). An intracranial aneurysm was also detected in the right MCA bifurcation from the screening magnetic resonance angiography (G).
