Various anastomosis and aberrant origins of the middle meningeal artery (MMA) have been documented in literature. However, there has been no report of its origin from the posterior inferior cerebellar artery (PICA) or its branches. In this report, we discuss an anomalous origin of the MMA from the PICA. Also, we discuss the embryological and anatomical development of the MMA. Imaging identification of the origin of the MMA is important while planning surgical and endovascular interventions in the region of the skull base.
各种硬脑膜中动脉(MMA)的吻合和异常起源在文献中已有记载。然而,MMA 起源于小脑后下动脉(PICA)或其分支的情况尚未有报道。在本报告中,我们讨论了 MMA 源自 PICA 的异常起源。此外,我们还讨论了 MMA 的胚胎学和解剖学发育。在颅底区域进行手术和血管内干预时,识别 MMA 的起源对于成像非常重要。
