BOHORQUEZ, Leonardo  and  VARGAS, Diana Carolina. Positron emission tomography/CT scanning in the diagnosis of neurosarcoidosis. Rev.Colomb.Reumatol. [online]. 2018, vol.25, n.3, pp.211-215. ISSN 0121-8123.  https://doi.org/10.1016/j.rcreu.2017.07.007.

The diagnosis of neurosarcoidosis is difficult because of its clinical and radiological polymorphism. Any part of the central nervous system may be affected, and imaging studies are usually inconclusive. The case is presented of a young patient with headache, bilateral facial paralysis, and subacute lymphocytic meningitis in whom, despite biochemical and imaging studies the origin was not identified. Using 18-PET-FDG helped to identify a hypermetabolic mediastinal adenopathy, with pathology reporting non-caseating granulomas, findings suggestive of sarcoidosis. This reflects its usefulness for the diagnosis and staging of the disease, especially in situations where there is no evidence from other imaging studies of extra-neural disease.
