Retinal haemorrhage and fatal stroke in an infant with fibromuscular dysplasia.

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 examination and it illustrates the diagnostic difficulty such cases may present.
