Abstract

A previously healthy 77-year-old Japanese man presented with a 2-week history of daily fevers peaking at 38°C, chills, hearing loss, and almost 10 kg of unintentional weight loss over 2 months. Pure tone audiometry showed mixed conductive-sensorineural hearing loss: right, 63.6 dB, left, 80.0 dB. Blood tests after admission showed a high myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) level (>300 U/mL), so we suspected ANCA-related vasculitis. The Japanese Otorhinolaryngology Society has recently been advocating the concept of otitis media with ANCA-associated vasculitis (OMAAV). Our case met the criteria proposed, leading to our diagnosis.
