| anonymous | Meningioma (100%), chordoid subtype | Positive for EMA,varying positivity for S100 and negative for GFAP. | 100 |
| anonymous | Chordoid meningioma (100%). | nil | 100 |
| anonymous | Meningioma, suggestive of chodoid variant (95%); Melanocytoma (5%) | Immunostaining for EMA (positive in meningioma); S100 and HMB45 (positive in melanocytoma) | 95 |
| anonymous | MENINGIOMA consistent with chordoid subtype 100%. | Meningeal lineage to be confirmed by positivity to EMA(may be focal for this subtype). | 100 |

| anonymous | Brain - Chordoid Meningioma 100% | nil | 100 |
| anonymous | Meningioma with microcystic pattern (WHO grade I) (100%) | Extensive sampling of the tumour in order to rule out atypical features and coagulative necrosis is needed. | 90 |

| anonymous | meningioma, grade 1. Probability: 100% | nil | 90 |
| anonymous | Meningioma 100% | Features of chordoid variant are present. Chordoid variant of meningioma (WHO grade II) shows greater likelihood of recurrence. | 100 |
| anonymous | Meningioma with area of chordoid features. | Chordoid features can be mixed with typical meningioma. Recurrence rate would be higher than typical meningioma. More extensive sampling of tissue and immunostain (MIB1) for proliferative activity would be useful in classification. | 100 |
