Abstract

A 47-year-old man with treatment-naive sarcoidosis underwent 18F-FDG PET/CT. The image revealed clearly abnormal uptakes in his lymph nodes, muscles, and lungs, consistent with lesions of sarcoidosis. The patient had no symptoms and was under observation without treatment for sarcoidosis. At a 2-year follow-up, he underwent another 18F-FDG PET/CT scan, which revealed that several lesions with abnormal FDG uptake had significantly decreased, and some lesions had completely disappeared. Because sarcoidosis frequently shows spontaneous recovery, FDG uptake may show spontaneously dynamic changes in the associated lesions.

摘要

一位 47 岁的初治结节病男性患者进行了 18F-FDG PET/CT 检查。图像显示他的淋巴结、肌肉和肺部有明显异常摄取，与结节病的病变一致。患者没有症状，也没有接受结节病的治疗，仅在观察中。在 2 年的随访中，他再次进行了 18F-FDG PET/CT 扫描，结果显示几个异常摄取 FDG 的病变明显减少，一些病变已经完全消失。由于结节病常表现为自发性恢复，FDG 摄取可能在相关病变中出现自发的动态变化。
