Abstract
An empty sella refers to a condition in which an arachnoid diverticulum extends into the sella, often causing reshaping and flattening of the pituitary gland and stalk.
This entity is frequently characterized as either a primary or secondary empty sella syndrome, depending on the etiology and associated conditions.
Suggested causes of primary empty sella (PES) include numerous congenital and developmental syndromes, congenital defects in the diaphragma sella, and chronic elevations in intracranial pressure (such as idiopathic intracranial hypertension). Defects of the diaphragma sella appear to be necessary—but not sufficient—in causing arachnoidal diverticula and PES.
