Brain CT (A,B) conducted on the day of symptom onset showing subarachnoid hemorrhage (red arrowhead on A,B) and DSA of antero-posterior view (C,E) and lateral view (D,F) obtained 7 days after symptom onset showing aneurysm at the P1-P2 segment of the left PCA before (red arrowhead on C,D) and after coil embolization (red arrowhead on E,F).

Computed tomography (CT) of the brain was conducted immediately and showed a subarachnoid hemorrhage (SAH) (Figures 1A,B). SAH and accepted regular treatment with intravenous mannitol and nimodipine, and the headache was greatly relieved. Seven days after headache symptom onset, the patient underwent digital subtraction angiography (DSA) examination under general anesthesia, and the result showed the presence of an aneurysm of the left PCA at the P1-P2 segments, measuring 4 x 5 mm with a neck of 1.5 mm (Figures 1C,D). Then, the patient underwent stent-assisted coil embolization of the aneurysm (Figures 1E,F).
Brain CT (A,B) conducted showing no localized hemorrhage or ischemic lesions after she had a migraine-like headache. Reexamination of DSA showing the coil was stable and there was no in situ thrombus (C,D).

Head CT was performed immediately showing no localized hemorrhage or ischemic lesions (Figures 2A,B). The patient was underwent DSA examination again, showing that the coil was stable and there was no in situ thrombus (Figures 2C,D).
EEG (A) Showed spike-and-slow wave complexes in the left occipital and temporal areas, and 1 month after the readministration with clopidogrel, EEG (B) showed normal.

Sixteen months after endovascular coiling treatment, the patient accepted EEG examination again in our department, and spike-and-slow wave complexes could be detected in the left occipital and temporal areas (Figure 3A). One month after the readministration with clopidogrel, EEG was reconducted, and neither epileptiform discharges nor asymmetric background activity was observed (Figure 3B).
