Intracranial meningioma surgery outcome--the impact of preoperative neuroimaging.
The present study is aimed at finding radiological parameters which could provide indirect information on invasive growth of meningioma, relevant enough to predict the possible risk of postoperative neurological deficit development. The cohort was composed of 40 consecutive adult patients of comparable general condition parameters (age 18-75 years, KRS 70-100, ASA 1-2) with meningiomas attacking with the whole of their volume solely the brain tissue. As follows from the outcome, meningioma growth in the eloquent area and the presence of peritumoral oedema are the two adverse parameters predicting the development of postoperative neurological deficit. In contrast, dural type of vascularisation, visible tumour-brain interface, meningioma growing in a non-eloquent area and the absence of peritumoral oedema are favourable predictive parameters. According to our results, if the last two of those parameters are present, the patient need not to be exposed to the risks of invasive selective angiography.
