Abnormal intracranial translucency (IT) (fourth ventricle) and a Blake's pouch cyst with normal brain stem cavity may be valuable first‐trimester call signs of defects in the skull base. Here, we report a case of presumptive two‐dimensional sonographic diagnosis of occipital cephalocele that was posed at the time of 11–13 weeks aneuploidy scan. The two‐dimensional sonographic finding elicited a detailed fetal neuroscan that was performed using either multiplanar mode or a novel three‐dimensional reslicing and lightening technique. The use of three‐dimensional sonographic software and offline “navigation” within the volume of interest enabled operators to capture a diagnostic snapshot of the condition, enhancing quality imaging and early detection of the encephalic lesion. © 2013 Wiley Periodicals, Inc.
