"The cerebellum, meaning "the little brain", sits at the base of the brain in the posterior cranial fossa below the tentorium and behind the brainstem."
"The AICA has a variable vascular territory depending on the size of the PICA (see AICA-PICA dominance) but usually supplies:"

"There are some variations in the PICA:"
"There are three major groups of bilateral veins that drain the cerebellum along with other structures of the posterior cranial fossa. Not unsurprisingly there is significant variation between patients and also between the left and right in the same patient."
