orbital encephalocele
a a  
Sonogram of a 33 week fetus with orbital encephalocele. Left orbit is disrupted by encephalocele (red arrow). Right orbit exhibits microtia (blue arrow). Encephalocele of left frontal lobe resulting in protruding orbit. Note dysgenetic brain and severely sloping forehead.  
a b a
In the coronal plane, neural tissue is visible protruding from left orbit.
a b a
Sagittal, coronal, and axial views demonstrate severely dysgenetic brain.
frontal encephalocele  
c d  
Protrusion of frontal lobe through calveric defect results in dysmorphic left orbit. Sagittal view demonstrates sloping forehead, microcephaly, and dysgenetic brain.  
d d  
Frontal lobe is entrapped by encephalocele, making neural tissue clearly visible outside the cranium, anterior to midface (arrow).

Postnatal preoperative photograph demonstrating encephalocele. Postnatal post-operative MRI demonstrating dysgenetic brain.
