Oncocytic Meningioma: Case Report of a Rare Meningioma Variant

Abstract: Oncocytic meningioma has been first identified in 1997 as a rare meningioma variant, composed predominantly of large meningothelial cells with abundant intracytoplasmic mitochondria. Here, we describe a 34-year-old male patient presenting with 2 weeks of progressive holocranial headache. Brain magnetic resonance imaging (MRI) revealed an extra axial solid-cystic expansive lesion in the left parieto-occipital parasagittal region, with intense vascularization. Histological and immunohistochemical analysis established the diagnosis. We also review briefly the pathological and radiological findings of this rare variant of meningioma as described in the literature.
