Non-accidental injury should be suspected and excluded in any infant found
to have intracranial and retinal haemorrhage of unknown aetiology. This can
be a sensitive issue for both medical staff and parents. We present a case
in which the underlying cause of intracranial and retinal haemorrhage was
fibromuscular dysplasia. It was a diagnosis made only at postmortem examina
tion and it illustrates the diagnostic difficulty such cases may present.
