[Bilateral temporal bone xanthoma associated with hyperlipidemia]

Presented clinical observation of a 42-year-old patient with bilateral xanthoma of the temporal bone, who has been treated for a long time for bilateral external otitis media, repeatedly mastoiditis. In this case, hyperlipidemia was detected only after the diagnosis of xanthoma was established. In this case, histological and clinical data helped to diagnose xanthomas and exclude chronic otitis media: the preservation of the auditory ossicles and hearing despite a large destruction of the temporal bone; satisfactory condition of the patient for many years in the presence of volumetric formations in both temporal areas extending into the cranial cavity, spreaded from the brain substance and not accumulating contrast according to computer and magnetic resonance imaging; normalization of hearing against the background of prolonged heating of the body - 'melting' of fats and opening the ear canal. Fistulas, through which a yellowish secret stood out either in the external auditory canal or in the behind-the-ear area, served as a kind of 'whisper valve', which made it possible to stop the pain syndrome and did not lead to the development of cerebral symptoms.
