Neurosarcoidosis presenting as ghost lesions in the CNS: a diagnostic dilemma

摘要

This article reports an unusual case of neurosarcoidosis presenting as a cerebellar mass lesion. Resolution of the lesion with steroids prompted further searches for disease outside the CNS. Pulmonary sar-coidosis was confirmed. It also reviews the key diagnostic aspects of neurosarcoidosis presenting as CNS ghost lesions, emphasizing the importance of attempting diagnosis of atypical CNS lesions without resorting to brain biopsy.
