Neurosurgical experience with magnetic resonance imaging in sellar lesions.

Abstract

41 patients with various sellar and parasellar lesions (pituitary adenomas, meningiomas, optic gliomas, craniopharyngeomas and granulomas), who underwent surgery consecutively, were studied by MRI investigations. In 10 patients post-operative MRI controls were performed. The information obtained by the MRI were compared with the other radiological investigations (especially coronar and axial high resolution CT), and the intra-operative findings. The advantages of MRI in the diagnosis of sellar lesion are demonstrated by exemplary cases.
