Course

Cerebral peduncle strokes — pure motor weakness, cranial nerve findings, and posterior circulation detection (Advanced)

Advanced course: strokes affecting the cerebral peduncle (midbrain motor pathways) can cause strong weakness with specific cranial nerve patterns. Learn what it looks like and how CT/MRI/CTA detect posterior circulation lesions

What you'll learn

  • Understand what the cerebral peduncle is (motor pathway highway)
  • Recognize possible symptom patterns (dense weakness + eye/face findings)
  • Understand why posterior circulation ischemia may need MRI DWI for detection
  • Ask questions about CTA/MRA vessel evaluation and monitoring
