Attraverso una valutazione retrospettiva di 26 casi di meningiomi intracranici abbiamo voluto correlare l'entità dell'edema perilesionale con determinati aspetti neuroradiologici.
La valutazione dei risultati è stata effettuata con metodi statistici ed è emersa una significativa correlazione fra l'entità dell'edema e la presenza di compressione corticale, l'apporto vascolare prevalente da vasi piali e, in misura minore, le dimensioni del tumore.
Questi rilievi possono risultare importanti al fine di dimostrare l'ipotesi di un ruolo attivo delle cellule neoplastiche nella genesi della sofferenza del tessuto cerebrale adiacente (edema citotossico).
