Summary of "Bilateral extradural PICA origins at the point at which the VA ascends between the transverse foramina of C-2 and C-1, simultaneously exist right double origin PICA: a rare case report and literature review."

The location of the origin of the PICA is highly variable. An extracranial origin PICA from the vertebral artery(VA) is not rare. But, the PICA originated extradurally at the point at which the VA ascends between the transverse foramina of C-2 and C-1 is one very rare anatomic variant. Double origin PICA (DOPICA) is another one very rare anatomic variant observed in 1% to 4% of patients in which 2 PICA branches converge distally.
