RESUMO
A child who had iron deficiency anemia(IDA) resulted from the prolonged breast feeding presented with left side hemiparesis following mild head injury. The serial computed tomography and magnetic resonance imaging showed right internal carotid artery territory infarction. It has been generally accepted that prolonged breast feeding causes IDA. A few cases of infarction caused by IDA have been reported. A few cases of cerebral infarction caused by mild head injury have been also reported. However, few have been reported nonhemorrhagic cerebral infarction caused by mild head injury associated with IDA from prolonged breast feeding. We reviewed the literature that prolonged breast feeding causes IDA and in this case, mild head injury could cause the cerebral infarction. We think that it is important to have clinical suspicion of cerebral infarction in a child with IDA from prolonged breast feeding who has mild head injury because early diagnosis is difficult.
