Computerized tomography in the evaluation of pituitary adenomas.

Computerized tomography during the past few years has been unequivocally been proven to be of extreme value in the evaluation of intracranial disease. Despite earlier reports, accuracy of diagnosis in the area of the sella turcica is found to be high despite the close proximity of both bony and air-containing structures. Correlation between computed tomographic images, angiography and pneumoencephalography has been performed and demonstrates that CT scans with a low margin of erro depict the relationships of pituitary adenomas to the surrounding brain parenchyma. The continued importance of angiography, and to some degree pneumoencephalography, in the diagnosis of pituitary tumors is discussed.
