title: A new pattern of arterial rete compensation of segmental basilar agenesis associated with carotid retia mirabilia: a case report (2010: 1b).
abstract: The carotid rete mirabile is a transdural arterial network centered at the parasellar area, in place of the intracavernous internal carotid artery (ICA), associated with hypoplasia or absence of the cervical and petrous ICA. Rare cases of vertebral rete mirabile associated with segmental agenesis of transdural vertebral arteries have been reported before. The authors present a new case of carotid rete mirabilia associated with segmental basilar agenesis compensated by a previously unknown pattern of arterial rete. Collateral flow, its efficacy and differential diagnosis are discussed.
