Intraparenchymal recurrence of a dural meningioma: association with rhabdoid alterations with aggressive biological and clinical behaviour

Abstract

A 47-year-old man underwent surgery for syncytial meningioma. Twelve months later neuroimaging demonstrated recurrence, showing an intra-axial ring-enhanced cystic lesion in the site of previous surgery. High-grade glioma was suspected. Neuropathologist's diagnosis was ‘intraparenchymal rhabdoid meningioma’. The case raises questions about behaviour of meningiomas and their differential diagnosis with gliomas.

Key words:

• Meningioma
• intraparenchymal
• rhabdoid tumour
• recurrent meningioma
