We present two cases of maternal hydrocephalus in pregnancy. In one case, the patient had no medical problems and had a spontaneous vaginal delivery of a normal neonate at term. In the second case, the patient had an uneventful pregnancy until 36 weeks when she presented to the labour ward with drowsiness and decreasing consciousness. She only recovered after emergency Caesarean section and revision of her ventriculo-peritoneal shunt. Her neonate although preterm had no anomalies and was sent home soon after birth with the mother.
