Case report

This is a case of the iniencephaly and acrania noticed at 13 weeks of pregnancy. Several anomalies could be seen: absence of the skull, with a posterior cystic lesion (Image 3) representing acrania; cervicothoracic rachischisis (Images 1, 2); marked angulation of the spine (image 2), retroflexed head (Image 3A). The parents opted for the interruption of the pregnancy. The final diagnosis was acrania and acrania with probable iniencephaly.
