The posterior cerebral artery (PCA) has been noted in literature to have anatomical variations, specifically fenestration. Cerebral arteries with fenestrations are uncommon, especially when associated with other vascular pathologies. We report a case here of fenestrations within the P1 segment of the right PCA associated with a right middle cerebral artery (MCA) aneurysm in an elder adult male who presented with a new onset of headaches. The patient was treated with vascular clipping of the MCA and has recovered well. Identifying anatomical variations with appropriate imaging is of particular importance in neuro-interventional procedures as it may have an impact on the procedure itself and consequently post-interventional outcomes.
文献中已指出大脑后动脉（PCA）存在解剖变异，特别是开窗畸形。有开窗畸形的脑动脉并不常见，尤其是当与其他血管病变相关时。我们在此报告一例老年男性患者，其右侧PCA的P1段存在开窗畸形，并伴有右侧大脑中动脉（MCA）动脉瘤，该患者因新发头痛前来就诊。患者接受了MCA血管夹闭术，术后恢复良好。在神经介入手术中，通过适当的影像学检查识别解剖变异尤为重要，因为这可能会影响手术本身以及术后的治疗效果。
