Lobar intracerebral hemorrhage + cerebral amyloid angiopathy (CAA) — imaging clues (microbleeds) and implications (Advanced)

Advanced course: some lobar hemorrhages in older adults are linked to cerebral amyloid angiopathy. Learn imaging clues (lobar microbleeds on susceptibility MRI), how CT/MRI contribute, and what questions to ask about recurrence risk and meds.

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 lobar vs deep hemorrhage patterns (high-level)
  • Recognize CAA as a possible cause of lobar hemorrhage in older adults
  • Explain MRI susceptibility sequences and microbleeds concept
  • Ask high-yield questions about recurrence risk and antithrombotic medication decisions

Key takeaways

  • Understand lobar vs deep hemorrhage patterns (high-level)
  • 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.
