摘要

54岁女性，有成人哮喘病史，表现为持续发热、皮疹、关节痛和感觉减退。实验室结果显示嗜酸性粒细胞升高（22%）。FDG PET/CT显示双肺实变摄取，与嗜酸性粒细胞性肺炎一致，并显示全身性肌炎，肌肉摄取增加（SUVmax 5.5），主要发生在下肢。根据2022年ACR/EULAR标准，诊断为嗜酸性肉芽肿病合并多血管炎（EGPA）。本病例强调了FDG PET/CT在显示嗜酸性粒细胞性肺炎和与EGPA相关的肌炎中的价值，提示其在诊断不明原因发热患者的EGPA方面的潜在作用。

Myositis Associated With Eosinophilic Granulomatosis With Polyangiitis Demonstrated by FDG PET/CT.

A 54-year-old woman with a history of adult-onset asthma presented with prolonged fever, rash, joint pain, and hypesthesia. Laboratory findings showed elevated eosinophils (22%). FDG PET/CT demonstrated uptake in consolidations in both lungs, consistent with eosinophilic pneumonia, and revealed systemic myositis with increased uptake (SUVmax 5.5) in muscles, predominantly in the lower extremities. Based on the 2022 ACR/EULAR criteria, she was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA). This case highlights the value of FDG PET/CT in demonstrating eosinophilic pneumonia and in myositis associated with EGPA, suggesting its potential role in diagnosing EGPA in patients with fever of unknown origin.
