A 72-year-old man presented with a cerebellar vermian tumor manifesting as headaches and vertigo. Angiography disclosed a vascular tumor fed by the superior cerebellar artery and an aneurysm of a primitive trigeminal artery. The patient underwent right occipital craniotomy to remove the highly vascular tumor via an occipital transtentorial approach. Association of a cerebral aneurysm with a hemangioblastoma has been reported previously in only five cases. Only three aneurysms were located on the feeding artery. The aneurysm in this case was not on the feeding artery. Simple coincidence might account for this case.
一名72岁男性因小脑蚓部肿瘤出现头痛和眩晕症状前来就诊。血管造影显示一个由小脑上动脉供血的血管性肿瘤以及一条原始三叉动脉的动脉瘤。患者接受了右枕部开颅手术，通过枕下经小脑幕入路切除了这个高血管性肿瘤。此前仅有5例报告过脑动脉瘤与成血管细胞瘤相关联。其中只有3个动脉瘤位于供血动脉上。本病例中的动脉瘤并不在供血动脉上。这种情况可能只是简单的巧合。
