From 9000 autopsies, three giant fusiform aneurysms of the basilar artery were found in middle-aged men with arterial hypertension, atherosclerosis, symptoms of encephalic circulatory disturbances, transient then permanent cranial nerves palsy. Neuroradiological investigations suggested a basilar dolichomegartery in one case. Anatomically, these unruptured giant aneurysms (respectively: 2, 2.5 and 4.5 cm largest transversal diameter) compressed the brainstem; a recent softening destroyed the midpons in one case, and both cerebral peduncles in another. A review of the literature underlined the paucity of similar cases, and the difficulty of differential diagnosis of giant basilar aneurysms detected only by neuroradiological investigations without anatomical verifications.
在9000例尸检中，发现3例基底动脉巨大梭形动脉瘤，患者为中年男性，患有动脉高血压、动脉粥样硬化、脑循环障碍症状、先是短暂性而后是永久性的颅神经麻痹。神经放射学检查提示1例为基底动脉延长扩张症。从解剖学上看，这些未破裂的巨大动脉瘤（最大横向直径分别为2厘米、2.5厘米和4.5厘米）压迫脑干；1例近期软化灶破坏了脑桥中部，另1例破坏了双侧大脑脚。文献综述强调了此类病例的稀缺性，以及仅通过神经放射学检查而无解剖学验证来检测巨大基底动脉瘤时鉴别诊断的困难。
