  • Subdural haemorrhage (SDH).
    • May be "thin film" type.
  • Retinal hemorrhage/nerve sheath hemorrhage.[3]
  • Hypoxic encephalopathy.

Other features

Subcortical slit-like haemorrhages:[4][5]

  • Classically frontal lobe.
  • Shear force.
  • Associated with shaken baby.

Related

Sinovenous thrombosis

  • Usually not associated with SDH.

DDx:

  • Coagulopathy.
  • Trauma.

Blood work of shock

  • Glucose - high (IV fluids).
  • WBC - high.
  • LFTs - high (ischemia).
  • INR - high (dilutional).
  • Hb - low (dilutional).
