Isolated neurosarcoidosis is a very rare disease, which makes up 5-15% of sarcoidosis cases. Hydrocephalus is a rare clinical feature with a prevalence of 6% among these patients. Considering neurosarcoidosis in the differential diagnosis of a unique parenquimal mass lesion could help in the early identification of this disease. We report the case of a 27-year-old African man who developed with a sole intracranial mass lesion mimicking radiologically a glioma, which finally came out as an isolated neurosarcoidosis. There is a difficulty in diagnosis when isolated neurosarcoidosis appears. In addition, the low prevalence of the disease entails a not standardized medical treatment. Natural outcome is poor even when hydrocephalus is resolved. Multimodal treatments including complete pharmacological treatment do not seem to assure a better outcome in these patients until date.
