Cerebellar infarct swelling — 4th ventricle compression, hydrocephalus, and follow-up imaging (Advanced)

Advanced course: large cerebellar ischemic strokes can swell and compress the 4th ventricle, causing hydrocephalus and brainstem pressure. Learn imaging terms, why serial CT/MRI matter, and red-flag symptoms.

If a patient develops new or worsening stroke symptoms, reduced consciousness, seizure, severe headache, airway/swallowing danger, or unstable vital signs, activate emergency response and follow local stroke escalation protocols.

Key takeaways

  • Explain why cerebellar infarcts can become dangerous over days due to swelling
  • Recognize imaging terms: 4th ventricle compression, hydrocephalus, mass effect
  • Explain how CT/MRI monitor posterior fossa swelling
  • Know red flags and what questions to ask about monitoring and repeat imaging

Key takeaways

  • Understand why cerebellar infarcts can become dangerous over days due to swelling
  • Advanced stroke care requires reconciling the clinical syndrome with timing, imaging, medication risk, patient context, and local pathway capacity.
  • A safe plan names escalation thresholds, responsible clinicians, patient-facing instructions, and the next step if results or symptoms change.
