We report a case of Neurosarcoidosis in absence of pulmonary features. It is estimated that less than 1% of patients have an isolated CNS involvement, without systemic evidence of disease. This case also had an unusual clinical presentation. A 28 years old female, presented with headache for 6 months. Her MRI Brain showed multiple ring enhancing lesions in the left cerebellum and vermis. Patient underwent posterior fossa craniotomy with biopsy of left cerebellar lesion which revealed non-caseating chronic granulomatous inflammation, consistent with sarcoidosis.
