MAGNETIC-RESONANCE-IMAGING OF A GLIOBLASTOMA OF THE OPTIC CHIASM - CASE-REPORT

Malignant optic glioma causing blindness was difficult to diagnose pri or to the introduction of computerized tomography (CT) and magnetic re sonance (MR) imaging, because earlier neuroradiological procedures oft en gave negative results and the clinical symptoms for this entity are not specific. In such cases only a craniotomy or postmortem examinati on revealed the tumor. The authors found no precise description in the literature of a malignant optic glioma diagnosed with modern imaging methods. They present a patient in whom biopsy results confirmed the C T and MR findings of glioblastoma multiforme of the optic chiasm.
