Tumor necrosis factor alpha (TNF-α) is a pro-inflammatory and immunoregulatory cytokine involved in the pathogenesis of several autoimmune disorders. Etanercept, a TNF-α antagonist (anti-TNF-α) acting as a soluble TNF-α receptor, has been associated with neurological demyelinating disorders. This paper aims to report an unusual case showing tumefactive central nervous system (CNS) inflammatory demyelination in a patient in the course of TNF -α antagonist therapy, requiring decompressive hemicraniectomy. This report is based on magnetic resonance imaging (MRI) findings and histology. A biopsy confirmed the inflammatory demyelinating nature of the lesions. The clinical presentation is unusual due to the severity of the disease process, requiring decompressive hemicraniotomy with a clinically favorable outcome. [ABSTRACT FROM AUTHOR]
