Fluorodeoxyglucose positron emission tomography (FDG PET) has been widely used in the assessment of malignancy. However, FDG is not tumor-specific and may be taken up by nonmalignant conditions such as sarcoidosis. Sarcoidosis is a systemic disease and extrapulmonary lesions are also present. However, laryngeal sarcoidosis is a rare manifestation of extrapulmonary sarcoidosis. A 60-year-old man with a history of previous sarcoidosis presented with hoarseness. PET imaging demonstrated increased FDG uptake in the larynx. The histologic examination revealed laryngeal sarcoidosis. We report a case of laryngeal sarcoidosis and emphasize the role of FDG PET.
氟脱氧葡萄糖正电子发射断层扫描（FDG PET）已广泛应用于恶性肿瘤的评估。然而，FDG并非肿瘤特异性的，可能会被结节病等非恶性疾病摄取。结节病是一种全身性疾病，也会出现肺外病变。然而，喉结节病是肺外结节病的一种罕见表现。一名有结节病病史的60岁男性因声音嘶哑就诊。PET成像显示喉部FDG摄取增加。组织学检查显示为喉结节病。我们报告一例喉结节病病例，并强调FDG PET的作用。
