Clinical syndrome suggestive of neurosarcoidosis withlaboratory support for CNS inflammation (elevated levels of CSFprotein and/or cells, the presence of oligoclonal bands and/ormagnetic resonance imaging (MRI) evidence compatible withneurosarcoidosis) andexclusion of alternative diagnoses togetherwith evidence for systemic sarcoidosis (either through positivehistology, including Kveimtest, and/or at least two indirectindicators from Gallium scan, chest imaging and serum ACE). Here, ACE is linked to neurosarcoidosis.
