FDG PET-CT imaging is increasingly accepted as a modality for evaluation of many malignancies, but FDG also can be accumulated intensely by inflammatory lesions. We present a case of a 60-year-old woman with intermittent fever, chills, fatigue, and dyschezia. CT scans indicated colon carcinoma with thoracic and retroperitoneal lymph node metastases. Whole body FDG PET-CT was performed to confirm and stage the malignant disease and showed intense FDG uptake in those lesions. However, histopathology confirmed tuberculosis. The literature describing FDG accumulation in constitutional tuberculous lesions is sparse, and one must be aware of patterns of FDG accumulation in tuberculosis in the diagnosing malignancies.
氟代脱氧葡萄糖正电子发射断层扫描-计算机断层扫描（FDG PET-CT）成像越来越被认为是评估多种恶性肿瘤的一种方式，但FDG也可被炎症性病变大量摄取。我们报告一例60岁女性，有间歇性发热、寒战、乏力及排便困难。CT扫描显示为结肠癌伴胸段及腹膜后淋巴结转移。行全身FDG PET-CT以确诊并对恶性疾病进行分期，结果显示这些病变中有强烈的FDG摄取。然而，组织病理学确诊为结核病。描述FDG在全身性结核病变中摄取情况的文献较少，在诊断恶性肿瘤时必须了解结核病中FDG摄取的模式。
