Delineation of pituitary adenomas by angiotomography.

The supra sellar extension of even small sized pituitary adenomas can be delineated with accuracy by angiotomography. This technique avoids the discomfort of pneumoencephalography in many patients. Angiotomography is also useful for the differential diagnosis of empty sellae.

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.
