A case of antenatal cerebral haemorrhage resulting from maternal alloimmunisation against fetal platelets.
Prenatal thrombocytopenia is a rare event and is generally due to fetal infection. In very rare cases, fetal thrombocytopenia is induced by maternal IgG directed against the fetal platelets. This alloimmunisation could lead to in utero bleeding. We now report such a case, in which fetal thrombocytopenia was complicated by a huge temporal lobe haematoma. Such a prenatal event is rare: only eight cases have been published, with only one pathologically confirmed case. Our patient is the second one in which neuropathological examination demonstrated prenatal intracerebral bleeding.
