Cerebral infarctions associated with intravenous use of methamphetamine

ABSTRACT

Methamphetamine is one of the most popular abuse drug in the South Korea. Intracranial hemorrhage or ischemic stroke have been well known as one of the complications with methamphetamine abuse. We experienced two cases with cerebral vasculopathy which had developed after intravenous use of methamphetamine. The first patient was a previously healthy 20-year-old woman, who was admitted because of drowsy mentality with left hemiparesis and dysarthria. The second patient was a 24-year-old man who was admitted because of seizure and left extremity weakness. They reported several intravenous administration of methamphetamine during previous months. In both case, brain CT showed cerebral infarction compatible with vascular territories. And also, carotid angiographys demonstrated that multiple intracranial vessels were involved with narrowing and stenotic nature, consisting with vasculitis in the both cases.
