Pediatrics · Emergencies: child abuse
Sample itemA 3-month-old has subdural haemorrhage, retinal haemorrhages and rib fractures with no history of trauma. What is the most likely diagnosis?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Abusive head trauma (shaken baby syndrome)
The triad of subdural haemorrhage, retinal haemorrhage and encephalopathy in an infant suggests inflicted shaking injury, often with posterior rib fractures. Evaluation includes a skeletal survey and child protection reporting. Metabolic and bleeding disorders should be excluded.
Option by option
A. Abusive head trauma (shaken baby syndrome) (correct)
Correct. This pattern suggests abusive head trauma.
B. Normal birth sequelae
Birth sequelae would not persist at 3 months in this way.
C. Vitamin K deficiency bleeding
Vitamin K deficiency does not cause rib fractures.
D. Osteogenesis imperfecta only
Osteogenesis imperfecta would show other features and rarely this triad.
