A 52-year-old man had biopsy-proven sarcoidosis of mediastinal lymph nodes. Cardiac sarcoidosis was confirmed on cardiac MRI with typical imaging features as delayed gadolinium enhancement. Follow-up FDG PET/CT with a 3-day pretest diet modification showed suppression of overall myocardial uptake of FDG but with multifocal abnormal FDG uptake in the myocardium regions corresponding to the previous MRI findings. Additional noncardiac active sarcoidosis involving multiple organ and lymph nodes were also visualized on FDG PET/CT.
一位 52 岁男性患有经活检证实的纵隔淋巴结结节病。心脏结节病通过心脏 MRI 得以确诊，其具有典型的影像学特征，即延迟钆增强。进行了 FDG PET/CT 检查，检查前三天进行了饮食调整，结果显示 FDG 在心肌整体摄取受到抑制，但在与先前 MRI 结果相对应的心肌区域存在多处异常 FDG 摄取。FDG PET/CT 还显示出累及多个器官和淋巴结的非心脏活性结节病。
