Abstract

Posterior pituitary ectopia is a very rare entity in the development of the pituitary gland. Several factors and multiple genes are associated with this entity causing both pituitary and extrapituitary abnormalities. Pituitary abnormalities can be various endocrine problems and extrapituitary abnormalities can be optic nerves and cerebellar hypoplasia, heterotopia, and abnormal vessels. This pictorial review represents the imaging manifestations of extrapituitary intracranial anomalies that can be associated with posterior pituitary ectopia.

Keywords

ectopic posterior pituitary - interruption of pituitary stalk - heterotopia - septo-optic dysplasia
