case_images: The imaging examinations before CIE. (A) MRI of the brain. (B) MRA detected the aneurysm in the communicating segment of the right ICA. (C) The DSA revealed an aneurysm with size of 7.4mm*6.1mm in the right ICA-communicating segment, and mild stenosis in right ICA-ophtalmic segment. (D) The DSA revealed a coiling embolization of the aneurysm.

case_images: MRI of the brain detected changes in signals that consist of multiple lacunar infarctions in the right basal ganglia and bilateral demyelination in the centrum semiovale (Figure 1A). Magnetic resonance angiography (MRA) of the brain indicated an aneurysm in the communicating segment of the right internal carotid artery (ICA) (Figure 1B). The DSA revealed an aneurysm with a size of 7.4 mm * 6.1 mm in the right communicating segment of ICA, and mild stenosis in right ophthalmic segment of ICA (Figure 1C). She received successful coiling of the aneurysm using two stent remodeling techniques (Figure 1D).
case_images: CTA performed 2 hours later indicated no occlusion of the right ICA (A,B).

case_images: CT of the brain performed immediately after the operation showed edema in the right cerebral hemisphere and involved the frontal, parietal, temporal, and occipital lobes, and there was no hemorrhage (Figure 3A). CT angiography (CTA) performed 2 h later indicated no occlusion of the right ICA (Figures 2A,B).
case_images: The non-contrast CT scans of the brain in CIE patient. (A) The brain CT scan performed immediately after the operation. (B) The brain CT scan performed in the following day. (C) The brain CT scan performed in the third day.

case_images: CT of the brain performed immediately after the operation showed edema in the right cerebral hemisphere and involved the frontal, parietal, temporal, and occipital lobes, and there was no hemorrhage (Figure 3A). CT angiography (CTA) performed 2 h later indicated no occlusion of the right ICA (Figures 2A,B). C, weakness in the left limb decreased (regained 0/5 strength), and suffered generalized tonic-clonic seizures for twice. CT reviewed persistent edema in the right cerebral hemisphere (Figure 3B). Fortunately, her clinical manifestations disappeared gradually on the third day and the follow-up brain CT showed resolution of the cerebral edema (Figure 3C).
