Background: Luckenschadel is commonly associated with Chiari II malformation and myelomeningocele. The aim of this case report was to revisit this entity. Case report: Antenatal imaging performed at 32 weeks gestation showed severe hydrocephalus with brain parenchymal thinning, cerebellar hypoplasia and lumbar myelomeningocele, suggestive of Chiari type II malformation. Stillbirth occurred before the pregnancy termination. X-rays showed a characteristic honeycomb appearance of the skull. The female 34-week-old stillborn was severely macerated and presented with thin and fenestrated skull, ruptured lumber myelomeningocele and diastematomyelia. Hydrocephalus could not be confirmed because of cerebral maceration. Histological examination did not reveal any significant visceral alteration. Conclusion: This case report highlights two key points. Luckenschadel should be kept in mind when Chiari II malformation is diagnosed. Autopsy with radiographic assessment is very useful in revealing this congenital defect which may escape prenatal detection.
