"Clear cell meningiomas appear similar to meningothelial (syncytial) meningiomas. However, the tumour cells have vacuolated cytoplasm; thus the moniker 'clear cell' 1. Histologically these tumours resemble other clear cell tumours such as oligodendroglioma, haemangioblastoma, germinoma, pleomorphic xanthoastrocytoma (PXA), clear-cell ependymoma and metastases from renal cell carcinoma 1."
