BACKGROUND: polymyositis is an idiopathic systematic disease characterized by a non-suppurative inflammatory process which attacks the skeletal musculature and manifests itself clinically by proximal and symmetrical muscular debility. It shows a variable incidence, approximately one in every hundred thousand inhabitants, predominately in females. PROCEDURES: a patient, 60 years, female and diagnosed with polymyositis was evaluated in the Otoneurology Sector of an Institution, referred having hearing difficulties in the right ear, tinnitus, anxiety, insomnia, difficulties in neck movement and shoulders and arms disseminated pain. The following procedures were carried out: anamnesis, otological inspection, audiological evaluation and vestibular exam. RESULTS: a) in the audiological evaluation there was sensorineural hearing loss from moderate degrees in the right ear and normal hearing thresholds in the left ear; b) in the imitanciometry there was a type "A" tympanometric curve and the presence of the stapedial reflexes, bilaterally; c) in the vestibular exam, semi-spontaneous multiple nystagmus and an absence of the inhibiting effect for ocular fixation were observed. CONCLUSION: alterations were observed in the accomplished exams, mainly in the vestibular exam, which demonstrated the importance for being carried out; and the sensitivity in the acquisition of the alteration which suggested an involvement of the central nervous system, contributing, thus, to a faster and more effective intervention and therapeutic accompaniment.
