Neurosarcoidosis and Multiple Sclerosis (MS) are both inflammatory disorders of the Central Nervous System (CNS), often presenting with overlapping clinical features, making differential diagnosis challenging. Neurosarcoidosis affects approximately 5-15% of systemic sarcoidosis patients and can mimic MS due to similar CNS involvement. Differentiation is critical, as treatment strategies vary significantly. Recent studies highlight that Cerebrospinal Fluid (CSF) analysis can aid in distinguishing these conditions. Key markers include elevated CSF white cell count, CSF lactate levels, and the absence of oligoclonal bands specific to MS. Radiological differences, such as distinct Magnetic Resonance Imaging (MRI) findings, also contribute to accurate diagnosis. While neurosarcoidosis is less common than MS, it remains a crucial differential diagnosis due to its potential for severe neurological outcomes. Further research is needed to refine non-invasive diagnostic criteria, potentially reducing reliance on CNS biopsy for definitive diagnosis.
