Cerebellar Tumor Like Lesion in a Patient With Neurosarcoidosis

Abstract

Sarcoidosis is a systemic granulomatous inflammatory disease that affects multiple organs, most commonly the lungs and lymph nodes. Neurosarcoidosis usually affects the nervous system with no clear systemic involvement. We present a 34-year-old gentleman with left-sided weakness, numbness, and imbalance, with cerebellar tumor like lesion on magnetic resonance imaging (MRI) of the brain. Based on mediastinal lymph node biopsy and after exclusion of other possible differential diagnoses, the patient has confirmed evidence of neurosarcoidosis. He was treated with pulse steroid therapy and subsequent immunosuppression with azathioprine and had excellent response.
