Particularly when present in a CNS/peri-CNS location, corded to nested array of tumor cells with vacuolated cytoplasm embedded in a fibrillar, chondroid, or myxoid matrix makes (A) extraskeletal myxoid chondrosarcoma, (B) chordoma, (C) skeletal myxoid chondrosarcoma, and (D) chordoid glioma plausible entities in the differential diagnosis of chordoid meningioma. CNS indicates central nervous system.
