Pathological correlation of Magnetic Resonance Imaging features in a classical case of lipomatous meningioma.

Meningiomas are common tumors, constituting about 20% of all primary brain tumors.[4] The histological subtype of lipomatous meningioma, resulting from lipid accumulation within meningothelial cells, is a well‐described but uncommon entity, representing approximately 0.3% of meningiomas.[2,3] In the World Health Organization (WHO) classification of tumors of the nervous system (2000), meningiomas with lipomatous changes were classified as metaplastic meningiomas (WHO Grade 1), and it has been documented that the clinical features, surgical management, and prognosis of lipomatous meningiomas are no different from those of other WHO Grade 1 meningiomas.[2] We report the case of a middle‐aged women presenting with magnetic resonance imaging (MRI) features of a classical “lipomatous” meningioma and correlate the radiological findings with the histopathological features of this uncommon tumor.
