Chondroblastoma of the temporal bone associated with a persistent hypoglossal artery.
A case of a chondroblastoma of the skull-base associated with a persistent hypoglossal artery (PHA) is presented. Neuroradiological findings of the PHA and the tumour are reported. The existence of a carotico-basilar communication such as a PHA should be recognized prior to skull base surgery because of the potential risk of cerebral ischemia.
