MNGI-30. RADIOLOGIC FEATURES ARE PROGNOSTIC FOR CLINICAL OUTCOMES OF CHORDOID MENINGIOMA

摘要

OBJECTIVES: Chordoid meningiomas are a rare histologic variant that follow an aggressive clinical course. Here, we examine histopathologic and radiologic features of chordoid meningiomas to identify risk factors for recurrence.METHODSRetrospective chart reviews were performed on 11 patients with chordoid meningioma and 15 patients with meningioma with focal chordoid features (<50% chordoid histology) who were treated at a single institution from 2000 to 2015. The median imaging follow-up was 45 months. A blinded radiologic review was performed on chordoid and 224 non-chordoid meningiomas from the same era.
