Empty sella syndrome

Empty sella syndrome is a syndrome caused by subarachnoid hernia into the pituitary fossa, compression and deformation of the pituitary and enlargement of the sella. Empty saddle syndrome was first used by Sheehan and summers in 1949 to describe postpartum pituitary necrosis. In the previous literature, it was also called sellar septal defect, intrasellar arachnoid cyst or diverticulum. Female patients are common, accounting for 80% ~ 90%. Common in pregnant women. The average age of onset is about 40 years old, which is rare in children.
