We report a case where fetal MRI using a low-field-strength magnet (0.5 T)
accurately confirmed a large extracranial vascular malformation, which was
suspected on antenatal US. Fetal MRI enabled better counselling of the pare
nts and allowed suitable plans to be made regarding method of delivery and
early management of the neonate. To our knowledge this is the first case of
an extracranial vascular malformation imaged using fetal MRI.
