Observations on peritumoral oedema in meningioma. Part II: Mechanisms of oedema production.
Meningiomas occurring in 160 patients were studied in relation to oedema production using computerised tomography. Statistically significant positive correlations with oedema production were found with tumours of large surface area, anterior parasagittal position, prominent vascularity, involving dural sinuses, and with short clinical history. Significant negative correlations were found with small tumour size and the presence of calcification. It is considered that hydromechanical factors predominate in oedema production with meningioma.
