Double origin of the posterior inferior cerebellar artery (PICA) has rarely been demonstrated by angiography in the peer-reviewed literature. Of the three previous reports, this PICA variant arose from the left vertebral artery. We report a right-sided, double-origin PICA.
小脑后下动脉(PICA)双起源在同行评审文献中很少通过血管造影显示。在之前的三份报告中,这种PICA变异起源于左椎动脉。我们报告一例右侧双起源PICA。
