[Prolactin-secreting adenomas. Radiologic signs].

The sellar and tomo-encephalographic changes in pituitary prolactin secreting adenomas are described on the base of 75 cases detected within a period of 2 years. In the diagnosis of smaller adenomas in which the sellar findings may be questionable, the value of fractionated encephalography is emphasized, and especially of frontal tomograms, in order to demonstrate a lateral bulging of the sellar diaphragm and a shift of the pituitary stalk to the opposite side.
