Abstract

Cerebral hemorrhage during fetal period may be related to various etiologies. The frequency of intraventricular hemorrhage in neonates is reported to be 25-45%. Neonatal alloimmune thrombocytopenia (NAIT) develops when fetal thrombocytes lack an antigen which is derived either from mother or the father. Typically affected newborns are healthy after birth and during early postnatal period, they may show moderate or severe symptoms including fetal intracranial hemorrhage related to the degree of thrombocytopenia.

A newborn with an antenatal diagnosis of fetal intracranial hemorrhage who postnatally was found to have NAIT was presented in this case report.

Key words: Fetal intracranial haemorrage, alloimmune thrombocytopenia, cranial ultrasonography
