Fluorodeoxyglucose (FDG)-positron emission tomography with computed tomography (FDG-PET/CT) is useful in disease monitoring of malignancies after therapy, while an FDG uptake may also be present in benign diseases. We herein demonstrate a case of disseminated Mycobacterium tuberculosis mimicking systemic metastasis of prostate cancer. This case highlights that clinicians should consider Mycobacterium tuberculosis in patients with prostate cancer who demonstrate multifocal FDG uptakes masquerading as metastasis, even when the chest photographs reveal a normal appearance and a sputum examination demonstrates negative results. An invasive surgical biopsy may be required and a pathological analysis would be critical in the diagnosis of Mycobacterium tuberculosis.
氟脱氧葡萄糖（FDG）正电子发射断层扫描与计算机断层扫描（FDG-PET/CT）在恶性肿瘤治疗后的疾病监测中很有用，而良性疾病中也可能出现FDG摄取。我们在此展示一例播散性结核分枝杆菌病例，其表现酷似前列腺癌的全身转移。该病例强调，对于前列腺癌患者出现多灶性FDG摄取伪装成转移的情况，即使胸部X线片显示正常且痰检结果为阴性，临床医生也应考虑结核分枝杆菌感染。可能需要进行侵入性手术活检，病理分析对结核分枝杆菌的诊断至关重要。
