Answer

The cerebellar hemispheres are supplied as follows:

  • Inferiorly by the posterior inferior cerebellar artery (PICA), arising from the vertebral artery (see the image below)

    Frontal projection from a right vertebral artery a Frontal projection from a right vertebral artery angiogram illustrates the posterior circulation. The vertebral arteries join to form the basilar artery. The posterior inferior cerebellar arteries (PICAs) arise from the distal vertebral arteries. The anterior inferior cerebellar arteries (AICAs) arise from the proximal basilar artery. The superior cerebellar arteries (SCAs) arise distally from the basilar artery prior to its bifurcation into the posterior cerebral arteries (PCAs).
  • Superiorly by the superior cerebellar artery

  • Anterolaterally by the anterior inferior cerebellar artery (AICA), from the basilar artery
