Abstract

Fetal and Neonatal Alloimmune Thrombocytopenia (FNAIT) is a disease that affects babies. In FNAIT, the platelet count is decreased because the mother’s immune system attacks her fetus platelets. A low platelet count increases the risk of bleeding in the fetus and newborn. FNAIT is the leading cause of severe thrombocytopenia in the fetus and neonate. The most severe complication of FNAIT is intracranial hemorrhage, which occurs in 10%-20% of symptomatic infants. If the bleeding occurs in the brain, there may be long-term effects. The Pathophysiology of atraumatic fetal Subdural Hematoma (SDH) remains unknown. It is extrapolated from the SDH of a shaken baby syndrome in infants. A detailed prenatal investigation is crucial to elucidate the underlying etiology, which may be associated with a better prognosis. We present a case of antenatally diagnosed SDH secondary to FNAIT that was normal up to one month after follow-up.
