Follow-up evaluation for cerebral aneurysms. MRI Brain: There are scattered foci of periventricular and cortical white matter T2 hyperintensities, which may represent chronic small vessel ischemic disease. There are prominent right inferior basal ganglia perivascular spaces. There is no evidence of acute infarction or mass lesions. The ventricles are unchanged in size. The imaged paranasal sinuses and mastoid air cells are unremarkable. The orbits are intact. There is hyperostosis frontalis interna with areas of prominent fatty marrow. MRA Brain: There is unchanged fusiform dilation of the right middle cerebral artery and the distal right internal carotid artery. There is a 5 mm wide aneurysm at the right carotid terminus. The base of the aneurysm also measures approximately 5 mm. There is an unchanged prominent infundibulum at the origin of the right lenticulostriate artery. There is no evidence of significant steno-occlusive lesions.
1. No evidence of acute infarction.2. Unchanged fusiform dilation of the right middle cerebral artery and the distal right internal carotid artery and a 5 mm wide aneurysm at the right carotid terminus.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
