Abstract

PURPOSE
The purpose of this study was to assess the usefulness of MRI in the evaluation of vascular changes of the meningioma.
MATERIALS AND METHODS
We retrospectively studied the MRI findings in 20 cases of intracranial meningiomas. The images were assessed for vascular hilum, vascular rim, sinus invasion, and vascular encasement. Cerebral angiograms were obtained in 15 cases and compared with MRI findings.
RESULTS
MRI was as accurate as angiography in detection of vascular hilum(MRl=8/20, Anglogram=9/15), vascular rim(MRl=14/20, Angiogram=9/15) and dural sinus invasion(MRl=4/6, Angiogram=5/6). MRI was superior to angiography in detection of vascular encasement(MRl=2/3, Angiogram=0/2) and cavernous sinus invasion(MRI=3/3, Angiogram=0/2).
CONCLUSION
MRI is an excellent noninvasive imaging modality in evaluating vascular changes of omas.
