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.

摘要

1992年，尤尼斯和萨瓦亚报告称，颅外软组织肿瘤、颅骨骨质溶解及颅内肿瘤组成的CT三联征是脑膜瘤恶性的征象。我们报告了3例具有相似三联征的新病例的临床及CT表现，确诊为恶性脑膜瘤。然而，我们对这一征象进行了重新定义，并认为只要排除转移，该三联征就是脑膜瘤恶性的明确指标。
