1 A: Axial T1 MRI without contrast demonstrates a large mass near the inferior left basal ganglia containing areas of bright signal (thrombus or slow-moving blood). The horizontal pulsation artifact indicates that this is an aneurysm as a tumor would not cause a MRI pulsation artifact. B: Axial T2 image shows mixed bright and dark T2 signal within this large aneurysm representing areas of flowing blood (dark signal) and slow-moving blood or thrombus (brighter signal). C: Frontal angiogram demonstrates a giant aneurysm arising from the ICA terminus/MCA. Source: Chapter 2.
