Özet

Fat storage in a meningioma occurs via two distinct processes: metaplastic change of meningotheliomatous cells into mature adipocytes, or microcystic change and lipidisation of meningioma cells. We report a case of a true metaplastic "lipomatous" meningioma. Differentiation of two distinct types of meningioma lipidisation and their differential diagnosis from other fat-containing pathologies such as liposarcoma, mucinous cell carcinoma, dermoid and epidermoid tumors are discussed with special reference to the presented case.
