[Neonatal intracranial hematoma in hemophilia A]

A case of subdural and intracerebral hematoma which appeared spontaneously in a neonate with severe hemophilia A is reported. This rare complication justifies some preventive measures in families at risk : antenatal ultrasonographic diagnosis of sex, vitamin K administration to the mother at the end of pregnancy and plasma assay for factors VIII and IX in the male neonate. Clinical and ultrasonographic examination of the intracranial content must be repeated during the first week of life and specific replacement therapy must be instituted if the clinical condition requires it.
