Although blister aneurysms represent a small percentage of all intracranial aneurysms, they are generally considered to be a more morbid and challenging entity than the more common saccular intracranial aneurysms. Despite this, the etiology of blister aneurysms is still unknown, though there are several theories. We present the case of a 54-year-old man who initially presented with vision loss and normal intracranial computed tomography angiography imaging. Only 16 days thereafter, he underwent rapidly progressive clinical decline, which was found to be due to the development and rupture of a de novo supraclinoidal blister aneurysm. Autopsy results showed fungal infection of the arterial wall by Mucorales fungi at the site of the aneurysm. Our case report supports the theory that blister aneurysms can be caused by fungal infection of the wall of the internal carotid artery.
尽管水泡状动脉瘤在所有颅内动脉瘤中占比很小，但与更常见的囊状颅内动脉瘤相比，它们通常被认为是更具病态且更具挑战性的病变。尽管如此，水泡状动脉瘤的病因仍然不明，不过有几种理论。我们报告一例54岁男性病例，该患者最初表现为视力丧失，颅内计算机断层血管造影成像正常。仅16天后，他的临床症状迅速进展性恶化，结果发现是由于一个新出现的鞍上水泡状动脉瘤形成并破裂所致。尸检结果显示，动脉瘤部位的动脉壁被毛霉目真菌真菌感染。我们的病例报告支持这样一种理论，即水泡状动脉瘤可能由颈内动脉壁的真菌感染引起。
