Past studies have found an association between cochlear hydrops or early Meniere’s disease and acute low-frequency hearing loss (ALHL) without vertigo. However, its mechanism remains unclear in some ALHL cases. This report presents a case of ALHL associated with iron-deficiency anemia (IDA). The patient was a 49-year-old female who had previously been treated with betamethasone for sudden hearing loss in the right ear. Eight months later, the symptoms recurred and cochlear hydrops was diagnosed. Isosorbide and betamethasone were administered orally, and intravenous hydrocortisone tapering was added 1 week later, but these treatments were ineffective. At the same time and subsequently, iron sucrose was intravenously administered for IDA, and the patient’s hearing loss gradually resolved within 2 months. In view of the increase in serum hemoglobin levels after iron therapy, this might have been the most effective treatment in this case. The hearing loss could therefore be associated with the patient’s IDA.
