title: Hypoplasia of multiple cerebral arteries: report of an unusual case.
abstract: We present a rare case of hypoplasia of the vertebral arteries bilaterally, of the basilar artery, of the posterior cerebral arteries bilaterally, and right-sided aplasia of A1 branch of anterior cerebral artery. The patient became symptomatic with sudden-onset headaches, likely caused by high hemodynamic stress. The origin of the hypoplastic cerebral arteries is uncertain, but the concomitant existence of them supports the congenital origin.
