Empty Sella Syndrome
What is empty sella syndrome?
Empty sella syndrome (ESS) is a
rare disorder that affects a structure in the skull called the sella turcica. This is a
bony structure at the base of the brain. It is where the pituitary gland is located.
With ESS, imaging tests show that the area looks larger than normal. And it is not
completely filled by the pituitary gland.
There are 2 types of ESS: primary
Primary ESS. The pituitary gland is
usually flattened. This type is more common in women who are obese and have high
blood pressure. It has also been linked to fluid buildup in the brain.
Secondary ESS. The pituitary gland
may be small because of a genetic change (mutation), injury, radiation therapy,
inflammation (hypophysitis), or surgery.
What causes empty sella syndrome?
Experts don’t know what causes
primary ESS. Secondary ESS may be caused by injury, radiation therapy, or surgery. ESS
is not a life-threatening illness. Only about 1 in 4 people known to have empty sella
syndrome have a primary hormone disturbance.
