title: Evaluation of the abnormal sella turcica.
abstract: Current neurodiagnostic and endocrine evaluation for pituitary tumors, empty sella syndrome, and parasellar lesions includes new techniques. Multidirectional polytomography of the sella turcica in detecting very small pituitary adenomas is important. Also, the role of computerized axial tomography (CT scanning) in defining size and extent of sellar and parasellar lesions is increasing. There has been a decline in the use of cerebral angiography and pneumoencephalography, especially the latter, in the diagnostic workup of these patients since the introduction of CT scanning.
