- Oncocytic Meningioma: Case Report of a Rare Meningioma Variant(2023) CASAL, Yuri Reis; TEIXEIRA, Livia Porto; BANDEIRA, Gabriela Alencar; PORCEBAN, Matheus Moreli; PAIVA, Wellingson Silva; GODOY, Luis Filipe de Souza; YAMAKI, Vitor Nagai; LUCATO, Leandro Tavares; ALVES, Venancio Avancini Ferreira; FRASSETTO, Fernando PereiraOncocytic 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.
- Atypical Virchow-Robin Spaces Mimicking Cystic Primary Brain Tumor - Clinical Report and Literature Review(2020) PICARELLI, Helder; NEPOMUCENO, Thales Bhering; CASAL, Yuri; YAMAKI, Vitor Nagai; TEIXEIRA, Manoel Jacobsen; FIGUEIREDO, Eberval GadelhaThe Virchow-Robin spaces (VRSs), which are often incidentally observed in modern structural neuroimaging examinations, are small cystic cavities that usually surround the small arteries and arterioles at the level of basal ganglia, the anterior perforated substance and the thalamic-mesencephalic junction. Typically, they have similar physicochemical characteristics to cerebral spinal fluid (CSF) and there is no contrast enhancement on brain CT and MRI images. Its real meaning is unknown, although some contemporary studies have suggested that it might be related to certain traumatic brain injury or several other central nervous system (CNS) disorders, as degenerative diseases. Occasionally, some wide and atypical VRS may be mistaken for primary cystic brain tumors, especially in the context of large and symptomatic lesions, multiple clustered cysts, cortical lesions and if there is adjacent reactive gliosis. The present paper reports four patients who were affected by atypical VRS mimicking brain tumors that required imaging follow-up or even a biopsy to confirm the diagnosis or to indicate the correct approach. Although it is not so unusual, one of them occurred concomitantly and adjacent to a diffuse glioma (co-deleted 1p19q, WHO-GII).
