Case ReportsLate hemorrhagic disease of the newborn as a cause of intracerebral bleeding.
We report a case of a 4-week-old female who presented with late hemorrhagic disease of the newborn (HDN). The newborn was previously healthy, and she received 1 mg of intramuscular vitamin K at birth. ⋯ Coagulation studies showed a deficiency of vitamin K-dependent coagulation factors, and the normalization of all clotting studies after administration of vitamin K confirmed the diagnosis of HDN. Our conclusions are that physicians must be alert to mild bleeding in newborns and that prophylaxis with 1 mg of intramuscular vitamin K at birth may be insufficient to prevent late HDN.
