The posterior inferior cerebellar artery (PICA) is normally a branch of the vertebral artery. In this rare case, the unilateral left vertebral artery continued its course as the left PICA, and an extremely small caliber left vertebral artery joined the righ vertebral artery to form the basilar artery. This rare feature of the PICA is demonstrated and its relation to neighboring structures is discussed. Also, the literature concerning the PICA is reviewed.
小脑后下动脉（PICA）通常是椎动脉的一个分支。在这个罕见病例中，左侧椎动脉单侧延续为左侧小脑后下动脉，一条管径极小的左侧椎动脉与右侧椎动脉汇合形成基底动脉。展示了小脑后下动脉的这一罕见特征，并讨论了其与邻近结构的关系。此外，还回顾了有关小脑后下动脉的文献。
