sella tur´cica a depression on the upper surface of the sphenoid bone, lodging the pituitary gland.
Sella turcica in the superior aspect of the sphenoid bone. From Dorland's, 2000.

emp·ty sel·la

a sella turcica, often enlarged, that contains no discernible pituitary gland; may be primarily due to an incompetent sellar diaphragm with compression of the pituitary gland by herniating arachnoid or secondarily due to surgery or radiotherapy.

The medial aspect of the temporal bone may fail to develop, resulting in a persistent lateral craniopharyngeal canal (also known as the Sternberg canal) between the middle cranial fossa and the pneumatised inferolateral recess of the sphenoid sinus.3 Idiopathic intracranial hypertension (pseudotumour cerebri) and empty sella syndrome are also known to occur in these patients,2 suggesting that chronically increased intracranial pressure with localised thinning of the bone may also play a role in the pathogenesis of this condition.4
