Sincipital encephaloceles are congenital herniations of cerebral parenchyma through a cranial defect. There are three main types 1,2:
- frontonasal encephalocele (~50%): more common in Asia and Latin America 4
- nasoethmoidal encephalocele (30%): more common in North America 4
- nasoorbital (nasolateral) encephalocele
History and etymology
Sincipital is a derivative of sinciput and relates to the frontal calvaria. It derives from the Latin words "semi" (half) and "caput" (head) 3.
Differential diagnosis
Consider other midline nasal region lesions, in particular nasal glioma.
