A mum claims the doctor's discovery of her daughter's one-in-a-million diagnosis was "completely accidental".
Ebby Tidswell, 30, was 28-weeks pregnant when she was told her unborn daughter Rosie had Vein of Galen Malformation (VGM).
The rare condition, which occurs during pregnancy, results in abnormal connections between blood vessels within the brain, affecting one in a million children born in the UK each year.
