Objective: We report a case in which coil embolization was selected for an aneurysm that caused subarachnoid hemorrhage but was difficult to judge whether it was true or false.
Case Presentations: A 78-year-old woman presented with severe subarachnoid hemorrhage. A wide-necked aneurysm was observed in the dilated internal carotid artery. We suspected senile atherosclerotic change, but blood blister-like aneurysm was also considered possible from the aneurysm morphology and dilation of the parent artery. Conservative treatment was initially selected, but as enlargement was noted in part of the aneurysm, coil embolization was performed as an emergency procedure, resulting in a stable postoperative course.
Conclusion: In case of urgency, endovascular treatment may be a permissible option when the judgment of whether the aneurysm is true or false is difficult.
