Antenatal imaging of a near-term fetus with primary acalvaria.
We report a near-term fetus with primary acalvaria, an extremely rare malformation characterized by the complete absence of the membranous neurocranium. Sonographic findings were considered consistent with this condition, which was confirmed by magnetic resonance imaging. Spontaneous vaginal delivery resulted in a fresh stillbirth, with an intact cranial sac.
