title: Megaloblastic anaemia in one of monozygous twins breast fed by their vegetarian mother.
abstract: Megaloblastic anaemia in infancy is uncommon in western countries. We describe a case of an exclusively breast-fed monozygous twin with severe vitamin B12 deficiency with haematologic and neurologic abnormalities. Treatment with vitamin B12 resulted in a rapid haematological and clinical improvement.
