title: Hyponatremia as presentation in a patient with neurosarcoidosis.
abstract: Sarcoidosis is an inflammatory disease with unknown cause characterized by non-caseating granuloma formations. It may present with bilateral hilar lymphadenopathy, skin lesions, eye and musculoskeletal system involvement. Hypercalcemia and hypercalciuria are important electrolyte imbalances resulting from sarcoidosis and sometimes they may cause nephrolitiasis and kidney failure. Hyponatremia, although being quite rare, has been found in some patients with sarcoidosis. Herein, we have reported a patient with neurosarcoidosis who presented with hyponatremia and responded well to corticosteroid treatment.
