[Vascular pathologies and vascular anatomical variants of the posterior cranial fossa].

CLINICAL/METHODICAL ISSUE: The posterior fossa is the location of some specific vascular pathologies and vascular anatomical variants that are important for radiologists to know and recognize. Vascular malformations that are also found in the supratentorial region have some divergent characteristics in the posterior fossa.

PRACTICAL RECOMMENDATIONS

Knowledge of the vascular anatomy of the posterior fossa and its variants is important for an understanding of vascular pathologies.
