Bilateral sudden sensorineural hearing loss as an initial presentation of myelodysplastic syndrome

This study reports an unusual case in which myelodysplastic syndrome presented bilateral sudden sensorineural hearing loss as the first symptom of the disease. The aural symptoms and signs such as tinnitus, dizziness, and hearing impairment of a hematologic disease are common. However, sudden hearing loss as the first manifestation of a hematologic disease is extremely rare. A 76-year-old woman presented with bilateral sudden hearing loss. The patient was found to have myelodysplastic syndrome during a workup for her hearing loss. Unfortunately, the patient's hearing loss did not improve after the medical treatment.
