Abstract

Spontaneous basilar artery dissection without vertebral artery involvement is a very rare clinical entity. We report three young patients who developed unilateral (cases 1 and 3) or bilateral (case 2) pontine infarction that produced hemiparesis and quadriparesis, respectively. The patients did not have conventional vascular risk factors or a history of trauma. The brain MRI and angiography findings were consistent with basilar artery dissection. We conclude that a possibility of basilar artery dissection should be considered when young patients with brainstem infarction are encountered even when there is no history of head trauma.
