Empty Sella Syndrome

Empty sella syndrome (pronounced: /ˈɛmpti ˈsɛlə ˈsɪndroʊm/) is a neurological disorder that involves the sella turcica, a bony structure at the base of the brain that surrounds and protects the pituitary gland.

Etymology

The term "empty sella" is derived from the Latin words "sella" meaning "seat" and "turcica" meaning "Turkish". The term "syndrome" is derived from the Greek word "syndromē" which means "concurrence of symptoms, concourse, road".

Definition

Empty sella syndrome is characterized by a sella turcica that appears to be empty on an imaging study, usually an MRI or CT scan. This is due to a herniation of the arachnoid membrane (a layer covering the brain) into the sella, often associated with an increased level of cerebrospinal fluid.
