Abstract

The CT triad of extracranial soft-tissue tumour, underlying osteolysis and an intracranial tumour was reported as a sign of malignancy in meningioma, by Younis and Sawaya in 1992. We report the clinical and CT spectrum of three new cases with a similar triad, confirmed to be malignant meningioma. However, we redefine this sign and suggest that this triad is an unequivocal indicator of malignancy in meningioma, provided metastases have been excluded.
