Brainstem infarction in a patient with internal carotid dissection and persistent trigeminal artery: a case report

The primitive trigeminal artery (PTA) is the most commonly described fetal anastomosis between the carotid and vertebrobasilar circulations. We report a 42-year-old patient presenting with internal carotid dissection, and imaging features of brainstem infarction. Based on the imaging studies we pres...

Description
Summary:The primitive trigeminal artery (PTA) is the most commonly described fetal anastomosis between the carotid and vertebrobasilar circulations. We report a 42-year-old patient presenting with internal carotid dissection, and imaging features of brainstem infarction. Based on the imaging studies we presume occlusive carotid dissection with extensive thrombosis within a persistent trigeminal artery as the cause of this brainstem ischemia.
