title: [An unusual MRI observation of neurosarcoidosis].
abstract: Sarcoidosis is a multisystemic granulomatous disease, characterized by the formation of an inflammatory lesion, the noncaseating giant-cell granuloma. Neurosarcoidosis represents only 5% of cases, but this figure is probably an underestimation. Diagnosis is difficult because of its clinical and radiological polymorphism. Magnetic resonance imaging (MRI) represents the "gold standard" of central nervous system exploration. We report here on an atypical example of primary neurosarcoidosis, according to MRI semiology, with preferential involvement of the Virchow-Robin perivascular spaces.
