We present a 54-year-old woman with 3-month history of skin rash and bilateral hearing loss. Multiple investigations including biopsy failed to reveal the underlying diagnosis of relapsing polychondritis, until 18 F-FDG PET/CT demonstrated a characteristic FDG activity pattern-the oto-rhino-tracheobronchial triad. The patient was subsequently diagnosed to have relapsing polychondritis and received treatment. The second FDG PET/CT revealed a differential response in different disease sites, which prompted an escalation of treatment.
我们现介绍一位 54 岁女性患者，其病史为 3 个月的皮疹和双侧听力损失。尽管进行了多项检查，包括活检，但未能明确复发性多软骨炎的潜在诊断，直到 18 F-FDG PET/CT 显示出特征性的 FDG 活性模式——耳-鼻-气管支气管三联征。随后，该患者被诊断为复发性多软骨炎并接受了治疗。第二次 FDG PET/CT 显示不同病变部位的反应存在差异，促使我们升级了治疗方案。
