[Neurosarcoidosis as the first manifestation of sarcoidosis: diagnosis difficulty. A case report].

Clinically apparent involvement of the nervous system occurs in a relatively small number of patients with sarcoidosis. The diagnosis of neurosarcoidosis is often difficult and particularly in patients who lack either pulmonary or systemic manifestations of sarcoidosis. Furthermore clinical and imaging features of neurosarcoidosis are extremely variable. We report a case of neurosarcoidosis which had been considered and treated at first as tuberculosis. Only the occurrence, two years later, of pulmonary manifestations of sarcoidosis enabled the diagnosis.
