Abstract Vitamin K deficiency in pregnant women causes intracranial hemorrhage (ICH) in fetuses. Fetal ICH frequently causes life‐threatening and persistent neurological damage. However, indicators for preventing fetal ICH are not established. Two pregnant women developed long‐term eating disorders caused by psychosis. They were administered intravenous fluid and vitamin supplementation, excluding vitamin K. The intracranial low‐hypoechoic area on fetal ultrasound was suggestive of fetal ICH due to vitamin K deficiency. Their neonates showed severe developmental delay. Laboratory analysis revealed a normal prothrombin time, but elevated protein induced by vitamin K absence II. Pregnant women who have eating disorders more than 3 weeks could develop fetal ICH due to maternal subclinical vitamin K deficiency. Illness duration and protein induced by vitamin K absence II of pregnant woman may be indicators for vitamin K administration to prevent fetal intracranial hemorrhage.
