A, Right internal carotid artery angiographic approach for coiling of a right ophthalmic ICA aneurysm (black arrowhead) in a 71-year-old woman using 7.78 mL/kg of iodinated contrast volume and a procedural time of 4 hours. Note the presence of fetal origin of the right posterior cerebral artery (black arrow). B, Gadolinium-enhanced FLAIR performed at 12 hours after endovascular coiling shows cortical and sulcal hyperintensity along the right middle cerebral artery territory (white arrows) and the right PCA territory (white arrowheads). C, Corresponding DWI shows no diffusion restriction. D, A follow-up unenhanced CT scan obtained on the same date shows no evidence of subarachnoid hemorrhage. E, Two-month follow-up Gd-FLAIR shows no residual abnormality.
