This article covers abusive head trauma in infants. It commonly goes by the name shaken baby syndrome, abbreviated SBS. A common alternate term is shaken-impact syndrome; this is advocated by some as it is uncertain shaking alone is sufficient to cause the classic pattern of injuries.

Defining features

Clinical triad

Classically described as:[1]

  1. Retinal haemorrhage.
  2. Subdural hemorrhage (SDH).
  3. Acute encephalopathy.
    • Some say brain swelling.[2]

Pathologic triad

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

Other features

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

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

Related

Sinovenous thrombosis

  • Usually not associated with SDH.

DDx:

  • Coagulopathy, as may be seen in sepsis.
  • Trauma.

Subcortical hemorrhage

  • Associated with cerebral vein thrombosis.[6]

Blood work of shock

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

Neonatal giant cell hepatitis

Main article: Neonatal giant cell hepatitis
