[Bilateral vestibulopathy and sensorineural hearing loss in necrobiotic xanthogranuloma, multiple myeloma and amiloidosis]. / Dvustoronnyaya vestibulopatiya i sensonevral'naya tugoukhost' u patsienta s nekroticheskoi ksantogranulemoi, mnozhestvennoi mielomoi i amiloidozom.

This article describes a rare case of necrotic xanthogranuloma in a 46-year-old patient who presented with the development of periorbital xanthelasms, progressive bilateral sensorineural hearing loss and bilateral vestibulopathy, followed by multiple myeloma and amyloidosis. For several years, the patient underwent standard rehabilitation for chronic sensorineural hearing loss and was fitted with a hearing aid. During hospitalisation for exacerbation of chronic bronchitis, monoclonal gammopathy was identified, and later, after careful examination and repeated biopsies, necrotic xanthogranuloma, multiple myeloma and AL-amyloidosis were confirmed. Targeted immunochemotherapy resulted in improvement of hearing and significant recovery of the vestibuloocular reflex bilaterally.
