Recurrent Intracranial Meningioma with Malignant Change and Extracranial Bone Metastasis: A Case Report

• Lee YH
• Sung NK

Abstract

In general, meningiomas are slowly growing benign neoplasms originating from specialized meningothelial cells in arachnoid granulation, but have a tendency to be locally invasive and recurrent. Meningiomas very rarely metastasize outside the nervous system, occurring in less than 0.1%. We report the CT and MR findings of a case of a solitary benign syncytial meningioma showing recurrent multiple tumors and malignant progression with eventual bone metastasis to rib after six surgical extirpations during six years.
