Multi-territorial posterior circulation ischemic stroke after cocaine intoxication.

Abstract

A 35-year-old man presented to the emergency department with altered mental status and bilateral tonicclonic seizures. Due to a progressive decrease in consciousness, he was intubated for airway protection. The patient’s relatives reported that he had used cocaine, leading to an initial suspicion of acute cocaine intoxication. However, a head CT scan without contrast revealed a hyperdense basilar artery sign without other signs of infarction (figure 1).
