GARCIA MOREIRA, Tania et al. Tomographic and anatomopathological correlation in sellar region tumors Ischemic stroke. Rev Cub Med Mil [online]. 2007, vol.36, n.4, pp. 0-0. ISSN 1561-3046.
The high prevalence of hypophyseal macroadenomas in the world motivated the conduction of this research, whose main objective was to show the value of computerized tomography in the presumptive diagnosis of the histological variety of hypophyseal macroadenomas, as well as of other less common tumors of the sellar region, taking into account the clinical picture.To this end, 124 patients operated on with the clinical and tomographic diagnosis of hypophyseal macroadenomas and other tumors of the sellar region, were studied. Age, sex, clinic, tomographic signs, and anatomopathological results were registered. It was observed a higher incidence of the hypophyseal adenomas (110). The non-secreting adenomas proved to be the predominant (41.1 %). Most of the patients were 30-50 years old. The female sex prevailed in the adrenocorticotropic adenomas and meningiomas, whereas males predominated in the GH and prolactin-producing adenomas. Within the tomographic signs, the erosion of the clinoids and the dorsum sellae, as well as hydrocephalus predominated in the non-secreting adenomas and the non-adenohypophyseal tumors. The adenomas (GH) stood out in the erosion of the floor and in the sellar ballooning, the same as the ACTH. The calcifications were frequent in the teratomas and craniopharyngiomas, as well as the non-homogenous capture of contrast, which was characteristic in these cases, as in Rathke's pouch cysts. Computarized tomography proved to have a great diagnostic value in the hypophyseal macroadenomas and other tumors of the sellar region, taking into consideration the clinical picture of the patient.
