title: Symptomatic salivary-rest cyst of the sella turcica.
abstract: Although ectopic salivary tissue in the posterior pituitary is frequently observed in microscopic examination at autopsy, this tissue is considered clinically insignificant. The authors report a case of sella turcica mass causing progressive menstrual irregularities and mild hyperprolactinemia in a 22-year-old woman. Magnetic resonance imaging revealed a 1.2 x 0.9 cm non-enhancing mass of the postero-inferior sella turcica. The lesion was isointense to brain on T1-weighted images and hypo- to iso-intense on T2-weighted images. Transsphenoidal exploration revealed that the cyst wall consisted entirely of normal appearing salivary gland. The clinical, radiographic, and pathologic features of this unique entity are discussed.
