[Potentials of noncontrast roentgenography of the skull in diagnosing small intrasellar hypophyseal tumors].

The results of non-contrast craniography in the diagnosis of small hypophyseal tumors are analysed. It was shown, that non-contrast craniography, i.e. ordinary craniography, radiography with the enlarged image, stereography and particularly tomography, is a safe method for diagnosing small intrasellar hypophyseal tumors. Radiodiagnosis of small intrasellar hypophyseal tumors is based on the determination of the pituitary fossa size and a detailed study of its state (structure, thickness, bicontour shape, disorder extent). To exclude hypophyseal microadenoma dynamic radiography is indicated every 6 months during 3 years to the patients with endocrine abnormalities, when the pituitary fossa size is within the upper limits of normal, provided the pituitary fossa walls are not affected.
