title: [Computer tomography diagnosis of space-occupying lesions in the area of the base of the skull].
abstract: 119 CT findings of examinations of the base of the skull conducted over a period of 52 months in 63 patients, were checked for their informative value. The CT findings were compared with clinical signs and symptoms and--if available--with findings from operations, biopsies and/or postmortem examinations (55 of 63 patients). For 42 CT findings, a total of 88 comparable findings obtained via conventional x-ray methods were available. This comparison showed a 66% superiority of CT over conventional radiography. The results point to a considerable superiority of CT both in the imaging of structures and in the detection of bony changes in the region of the base of the skull.
