Empty sella syndrome is the condition when the pituitary gland shrinks or becomes flattened, filling the sella turcica with cerebrospinal fluid instead of the normal pituitary. [2] It can be discovered as part of the diagnostic workup of pituitary disorders, or as an incidental finding when imaging the brain.
The empty sella sign occurs due to herniation of the subarachnoid space into the sella turcica, displacing the pituitary gland and allowing CSF to occupy the space. [3] This phenomenon is often linked to the following mechanisms: [4] Primary empty sella syndrome occurs without an underlying cause or pituitary pathology. It is associated with a ...
The failure to breastfeed and amenorrhea no more periods, were seen as the syndrome (a collection of symptoms), but we now view Sheehan's as the pituitary failing to secrete 1-5 of the 9 hormones that it normally produces (the anterior (front) lobe of the pituitary produces FSH, LH, prolactin, ACTH (Adreno-cortico-trophic hormone),TSH (Thyroid ...
Empty sella syndrome is the condition of a shrunken or flattened pituitary gland.. Since the sella turcica forms a bony caudal border for the pituitary gland, a pituitary tumor usually extends upward in the rostral direction into the suprasellar region.

In IIH these scans typically appear to be normal, although small or slit-like ventricles, dilatation and buckling [18] of the optic nerve sheaths and "empty sella sign" (flattening of the pituitary gland due to increased pressure) and enlargement of Meckel's caves may be seen.
The pituitary gland is located in a recess in the skull base known as the sella turcica ("Turkish saddle", after its shape). It is attached to the hypothalamus, a part of the brain, by a stalk that also contains the blood vessels that supply the gland. It is unclear why pituitary tumors are five times more likely to bleed than other tumors in ...
It sits in a protective bony enclosure called the sella turcica, covered by the dural fold diaphragma sellae. [4] The pituitary gland is composed of the anterior pituitary, the posterior pituitary, and an intermediate lobe that joins them. [5] The intermediate lobe is avascular and almost absent in humans. In many animals, these three lobes are ...
