[The middle meningeal blood supply to the posterior fossa (author's transl)].

The middle meningeal artery can sometimes supply the complete vascularisation of the posterior fossa, i.e., the dura mater of the cerebellar fossa and the tentorium cerebelli. The authors present an anatomic and radiologic correlative study based upon an unusual case where the middle meningeal artery arose from the ascending pharyngeal artery and vascularised the entire posterior cerebellar fossa.
