An exam may show problems with one or more nerves. A history of sarcoidosis followed nerve-related symptoms highly suggests neurosarcoidosis. However, symptoms of the condition can mimic other medical disorders, including diabetes insipidus, hypopituitarism, optic neuritis, meningitis, and certain tumors.lso known as: Sarcoidosis-nervous system. Neurosarcoidosis is a complication of sarcoidosis in which inflammation occurs in the brain, spinal cord, and other areas of the nervous system.
Sarcoidosis is a systemic disorder of unknown cause that is characterized by its pathological hallmark, the noncaseating granuloma. Its presenting features are protean, ranging from asymptomatic but abnormal findings on chest radiography in many patients to progressive multiorgan failure in an unfortunate minority.enetic factors appear to play a part in the pathogenesis of sarcoidosis. However, it is unlikely that any single gene is responsible. Conceptually, it appears likely that genetically predisposed hosts are exposed to antigens that trigger an exaggerated cellular immune response and the formation of granulomas.
