Acalvaria: A rare congenital malformation

Acalvaria is described as a rare congenital malformation in a 1-month-old female baby who presented with classical clinical features of soft, lax skull as a result of absent skull bones and associated muscles. Acalvaria is usually a fatal anomaly and is rarely discussed in English literature. Thus, we herein report a living case of acalvaria along with a review of the literature.
