Sudden bilateral hearing loss – an unusual cause

Introduction Sarcoidosis is a chronic disease of unclear etiology associated with the formation of non-caseating granulomas. Pulmonary, ocular or lymphatic manifestations are most common. Rarely, there are neurological symptoms (about 5%). If neurosarcoidosis is present, it usually affects the facial or optic nerve. Hearing disorders are present in only 20% of cases.
