Splenium (posterior corpus callosum) strokes — disconnection symptoms and MRI localization (Advanced)

Advanced course: posterior corpus callosum (splenium) lesions can cause disconnection symptoms (reading/writing integration, visual information transfer) and are often best seen on MRI. Covers ischemic vs hemorrhagic detection and differential diagnosis.

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 corpus callosum as inter-hemispheric connection (high-level)
  • Recognize that splenial lesions may cause subtle cognitive/visual integration deficits
  • Explain why MRI is often needed and CT may be unrevealing early in ischemia
  • Know differential diagnoses and what questions to ask

Key takeaways

  • Understand corpus callosum as inter-hemispheric connection (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.
