摘要

Gout is the most common cause of monoarthritis in men occurring classically in the great toe and the knee.Extra-articular gout manifestations are rare.Only a few cases of head and neck urate c～stals deposits have been described in the literature.Precipitations in the middle ear cause conductive hearing loss with common otoscopic anomalies and difficult imaging diagnosis.We report a case of a healthy 58-years-old man with a middle ear urate deposit causing a progressive hearing loss as the very first symptom of gout.The nature of the deposit was unsure on computer to-mography (CT) due to atypical density.The final diagnosis was revealed after surgical procedure and histologic examination.A review of the literature is also presented.Seven cases of middle ear urate deposit as the first symptom of gout were found and compared.Progressive conductive hearing loss in middle-aged patients with abnormal otoscopy and middle ear atypical density mass on CT scan must lead to a minimal surgical procedure with a histologic exami-nation to exclude urate crystals deposits.
