  • Title: [Hypophysis volume in computerized tomography and clinical grounds for diagnosing a primary completely empty sella turcica].
    Author: Krzysiek J, Gregorczyk A.
    Journal: Przegl Lek; 1990; 47(9):637-41. PubMed ID: 2287750.
    Abstract:
    Computerized tomography (CT) of the sella turcica was performed in 106 women with hypothalamic-hypophyseal-ovarian hypofunction, aged from 15 to 50 years. In each patient we evaluated tomographically hypophyseal volume and subarachnoid space cistern invaginated into the sella turcica. We analysed statistically the incidence of amenorrhea, infertility, obesity and arterial hypertension in five groups of patients classified according to hypophyseal volume i.e. from below 100 to over 400 mm3. Is was found that hypophyseal volume of women in the so-called empty sella turcica that could correlate significantly with obesity and arterial hypertension was up to about 200 mm3, and in case of amenorrhea and infertility below 100 mm3. In case of empty sella turcica in women with amenorrhea mean hypophyseal volume was significantly lower (about 194 mm3) than in menstruating women (about 248 mm3). Invagination of cisterns of the cerebral basis into the sella turcica equal to or exceeding three time hypophyseal volume in about 82% was associated with its small size i.e. below 150 mm3. Basing on our analysis it seem justified to assume that hypophyseal volume up to 150 mm3 is a CT criterion of diagnosing completely empty sella turcica.
