Presentation transcript:

A 23-year-old woman woke up with a complete hemiplegia. A 23-year-old woman woke up with a complete hemiplegia. Following a positive urine analysis, she admitted having taken considerable amounts of cocaine the night before. MR imaging demonstrates an MCA branch ischemia including involvement of the basal ganglia. T1-weighted postcontrast scans demonstrate abnormal vessel wall enhancement in the right MCA (arrowheads), and the time-of-flight MRA shows some mild irregularities of the distal M1, potentially testifying to acute drug-induced vasculitis as the most likely cause for the ischemia (arrows).
