Meningocele, Cranial - Frontoethmoidal

Summary   Ultrasound Features   Differential Diagnoses   Syndromes   Images 1   Show All

Frontonasal dysplasia (median facial cleft syndrome), which may be inherited as an autosomal dominant condition, may present with a frontal encephalocele in addition to the characteristic findings of a notched and broad nasal tip, hypertelorism and median cleft palate. Amniotic band sequence is a sporadic condition in which fragments of ruptured amnion may cause fetal deformation, including encephalocele formation, cleft lip and amputation of the extremities. Most frontoethmoidal cephaloceles are closed, skin covered defects. Failure of endochondral bone development in atelosteogenesis, a generalised lethal chondrodysplasia, has also resulted in frontal cranial defects.
