Overall the features are that of a WHO grade I (capillary) hemangioblastoma. Characteristic stromal cells are seen in figure 7, while the remaining cells have clear or vacuolated cytoplasm between abundant sinusoidal or capillary vessels. The only differential diagnosis is microcystic meningioma. GFAP-positive, S100-negative, and EMA-negative are good for hemangioblastoma and not good for meningioma. Chordoid meningioma's characteristic features are cords of epithelioid neoplastic cells in abundant myxoid background. The cytoplasm of neoplastic cells is not vacuolated or clear.
