title: [Computed tomographic diagnosis of diseases of the pituitary region].
abstract: Because of the high density and spatial resolution it allows, CT scanning has come to play a key role in the diagnosis of diseases of the pituitary region. While the extension of macroadenomas is regularly detected, only meticulous techniques using coronary scanning following intravenous bolus injection of contrast agent coupled with knowledge of artefacts and normal variations can allow sufficient certainty in the diagnosis of intrasellar lesions. In this respect, the finding of a localized, round hypodense region within the pituitary is of major importance. The so-called indirect signs of a pituitary mass are of minor significance. Demonstrations of typical changes in the CAT scan in combination with the clinical and hormonal findings can contribute to the differential diagnosis of diseases of the pituitary region.
