Two Cases of Rare Basilar Hypoplasia

Abstract In this article, we report two cases of basilar artery hypoplasia; the first case was a primitive trigeminal artery, and the second was an isolated basilar artery hypoplasia. Both patients had general neurologic disturbances, including periodic intention tremor of the left hand. Our data underscore the utility of complementary time of flight (TOF) magnetic resonance and multidetector computed tomography (MDCT) angiography as reliable first detection methods for steno-occlusive diseases and in cases of suspected congenital vascular anomalies.
