Hidradenitis suppurativa is an inflammatory disease associated with subcutaneous nodules/abscesses that occur commonly in the axillary, inguinal, and perineal regions. We describe a case of a 64-year-old man presenting for F-FDG PET/CT for staging of a left vocal cord squamous cell carcinoma. The scan showed uptake in the left vocal cord malignancy and multiple hypermetabolic subcutaneous foci in the right axilla, right buttocks, and scalp in known locations of skin lesions related to hidradenitis suppurativa. This case illustrates an unusual inflammatory cause of F-FDG incidental uptake that should not be mistaken for metastases.
化脓性汗腺炎是一种与皮下结节/脓肿相关的炎症性疾病，常见于腋窝、腹股沟和会阴区域。我们描述了一例 64 岁男性，因左声带鳞状细胞癌分期行 F-FDG PET/CT 检查。扫描显示左声带恶性肿瘤摄取 F-FDG，以及右侧腋窝、右侧臀部和头皮多处高代谢皮下病灶，这些病灶位于与化脓性汗腺炎相关的已知皮损部位。本例说明了 F-FDG 偶然摄取的一种不常见的炎症性原因，不应误诊为转移。
