Basilar Artery Thrombosis on Brain MRI

Basilar artery thrombosis is a rare cause of ischemic stroke which can cause devastating and fatal outcomes. Prodromal symptoms may include loss of vision, diplopia, dysarthria, vertigo, hemiparesis, paresthesias, imbalance, and convulsive-like movements, which may precede basilar artery thrombosis by several days or even months. Loss of the flow void on T2 brain magnetic resonance imaging (MRI) sequences is an early sign of basilar artery thrombosis.1,
