ABSTRACT

Sarcoidosis is a systemic granulomatous disease of unknown etiology, that affects principally the lungs, lymph nodes and skin during the third and fourth decades of life. The central nervous system compromise (Neurosarcoidosis) is considered a negative prognostic factor, and it occurs in 14% to 27% of the patients with Sarcoidosis. Magnetic Resonance (MR) and Computed Tommography (CT) findings are non specific for Neurosarcoidosis, but they turn to be of great value when the clinical suspicion of this disease is high. The purpose of this article is to show examples of neurosarcoidosis affecting the spinal cord, the Virchow-Robbin perivascular spaces, the orbits, the hypothalamichypophiseal region, menninges and other less common regions, using CT and MR. A review of the literature about this subject is also presented. We believe that MR with intravenous Gadolinium administration is an extremely useful tool for the diagnosis of this disease, and in obscure cases it gives the chance to select the exact location for performing a diagnostic biopsy. Treatment follow up is also achieved by this method.
