 Brain MRI:No evidence of acute ischemic or hemorrhagic lesion on this scan.Extensive non specific small vessel disease. No change since prior exam.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. The paranasal sinuses and mastoid air cells are clear.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate the right ACA A2 segment aneurysm.Measured size of the aneurysm appears to be about 2.8mm x 3.6mm which is slightly bigger than prior scan (2.9mm x 3.2mm).There is no other aneurysm seen.No evidence of significant intracranial arterial luminal stenosis.
Right ACA A2 segment aneurysm was redemonstrated.The size of aneurysm appears to be slightly bigger (3.0mm to 3.6mm), however, due to technical parameter differences and scan plane differences, this could be interpreted as no significant interval change since prior scan.
