The aim of the study is to define radiological parameters which may indirectly indicate invasive expansion of a meningioma and thus forecast potential risks of postoperative neurological deficits. The study group includes 40 adult patients in comparable physical conditions (age 18–75, CRS 70–100, ASA 1–2) with meningiomas, affecting the brain tissue only. The results indicate that unfavorable parametres, predicting potential postoperative neurological deficits include: growth of a meningioma in eloquent regions and presence of a peritumoral oedema. Positive parametres, indicating that no neurological deficit would arise, include: dural supply, visible brain-tumor barrier, non-eloquent location of a meningioma and absence of a peritumoral oedema. The study results suggest that provided the two last parametres are present, a patient need not be exposed to risks of invasive selective angiography.
Key words: intracranial meningioma – eloquency – peritumoral oedema – brain-tumor barrier – dural vascularization type
