Abstract
This chapter includes (1) Extracranial C1/2 level origin of the posterior inferior cerebellar artery (PICA), (2) Foramen magnum level origin of the PICA, (3) Duplicate origin of the PICA, (4) Duplicated PICA, (5) Bihemispheric PICA, (6) PICA-anterior inferior cerebellar artery (AICA) anastomosis (vertebrobasilar junction large arterial ring), (7) Common trunk of the AICA-PICA (PICA or AICA aplasia), (8) Duplicated AICA and early bifurcated AICA, (9) Duplicated superior cerebellar artery (SCA) and early bifurcated SCA, and (10) SCA arising from the posterior cerebral artery. There are 13 figures and 2 illustrations.
As mentioned above (Sects. 5.1.3, 5.2.3 and 5.3), the cerebellar arteries are rarely supplied by the ICA and ascending pharyngeal artery.
