title: Use of contrast infusion in cranial extracerebral computed tomography.
abstract: Previous reports have demonstrated the lack of enhancement of extracerebral cranial lesions. Six patients are presented in whom the orbits, nasopharynx, temporal bones and paranasal sinuses were scanned and the intracranial extracerebral component of lesions in these areas delineated with contrast infusion. As well, two tuberculum sphenoidale meningiomas are presented to demonstrate the importance of visualizing the suprasellar region when performing orbital scans.
