Sudden sensorineural hearing loss as the first manifestation of chronic myeloid leukaemia: case report.
BACKGROUND
Sudden sensorineural hearing loss rarely occurs in patients with chronic myeloid leukaemia.


METHODS
We present a case report of a patient who presented with sudden sensorineural hearing loss as the first manifestation of chronic myeloid leukaemia, and review the mechanisms responsible for sudden sensorineural hearing loss in leukaemic patients.


RESULTS
A 31-year-old female presented to our clinic with unilateral sudden sensorineural hearing loss and tinnitus. Pure tone audiometry revealed profound sensorineural hearing loss in the left ear at all frequencies. During an investigation into her hearing loss, the patient was found to have chronic myeloid leukaemia.


CONCLUSIONS
Every case of sudden sensorineural hearing loss must be carefully evaluated, and haematological disorders must be considered in the differential diagnosis of sudden hearing loss.
