A 67-year-old female visited our hospital with a complaint of progressive bilateral hearing loss and recurrent attackes of vertigo. An audiogram showed bilateral sensory neural hearing loss with positive recuruitment phenomenon. The caloric test showed bilateral canal paresis. The galvanic body sway test showed a normal response. From these results, we concluded that the hearing loss, dizziness and equilibrium dysfunction were due to a disorder of the inner ear. The results of a glycerol test and furosemide VOR test suggested endolymphatic hydrops in the inner ear. The patient was treated with steroid and prostaglandin I2. Her dizziness subsequently disappeared, but her hearing loss was not improved. After discharge from our hospital, she entered another hospital because of a high grade fever and muscular pain. Laboratory data suggested an autoimmune disease and renal failure. She was diagnosed with periarteritis nodosa on the basis of clinical findings and pathological findings following a kidney biopsy.
