Frontal encephalocele and the nasal cavity.

ABSTRACT

Congenital encephaloceles are rare lesions which are often present at the occipital region. Occasionally, they are encountered anteriorly where they may erode through the base of the skull or through a congenital defect in it and appear as a nasal polyp. We describe a case of an anterior basal encephalocele which presented with hypertelorism and was mistaken for a nasal polyp.
