Trans‐sphenoidal and sphenoethmoidal encephalocele: Report of two cases and review of the literature

Abstract

Basal encephaloceles are the least common form of encephalocele. Due to the critical position of the bony defect, visual and endocrinological abnormalities are frequently associated with basal encephaloceles. There is significant confusion in the classification of basal encephaloceles, particularly among trans‐sphenoidal, sphenoethmoidal and intrasphenoidal subtypes. Two cases of basal encephaloceles are presented (one trans‐sphenoidal and one sphenoethmoidal), along with a review of the literature. The relationship between the basal encephaloceles and endocrinological abnormalities is also emphasized.
