Prognosis
Usually babies with this malformation do not survive past birth. However, there have been cases of survival. As of 2004, there were only two reported living cases. Of these two, one was severely retarded and disabled. The status of the other was unreported. If the fetus progresses to full term, there is the risk that he will have head trauma from the pressure applied to head while being delivered. A few other cases of acalvaria have been reported, which did not progress to birth. In addition, to the lack skull cap, there were brain malformations present in each case, and all of the pregnancies were terminated either electively or the fetuses were spontaneously aborted.
