Focal cerebritis with vasculitis mimicking a high-grade glioma: A case report

Abstract

Cerebritis is an inflammatory reaction in the brain which can be localized or diffuse and can be secondary to various etiologies like granulomatous demyelinating infections, vasculitis or neoplastic. Identifying the aetiology is very essential for the proper treatment. We report a case of 24 years male patient, who came with a history of headaches for 3 months. CT scan revealed intra-axial hypodense lesion suggesting high-grade glioma, which on histopathological examination revealed reactive gliosis with diffuse lymphocytic infiltrate and perivascular lymphocyte collection.
