The F-18 fluorodeoxyglucose positron emission/computed tomography (FDG PET/CT) has become an established diagnostic imaging for malignancy. However, there are other diseases that can also be identified with FDG, some of them are infections such as tuberculosis. In this case report, two patients showed multiple hypermetabolic tuberculosis lesions on FDG PET/CT, with one of the patients having history of malignancy. The objective of the present case report is to emphasize the need to use other differential diagnosis techniques for tuberculosis especially in tuberculosis-endemic countries when interpreting FDG PET/CT. By analyzing diagnostic imaging alone, there is a high chance of misinterpreting asymptomatic tuberculosis patient as having malignancy. Therefore, there is need for correlation with clinical data as well as other imaging modalities and PET/CT with more specific tracer in order to differentiate malignancy from benign disease such as tuberculosis.

FDG PET / CT上恶性样病变的假阳性结果：结核病患者的病例报告

F-18氟脱氧葡萄糖正电子发射/计算机断层扫描（FDG PET / CT）已成为恶性肿瘤的公认诊断影像。但是，还有其他疾病也可以通过FDG进行鉴定，其中一些是感染，例如结核病。在该病例报告中，两名患者在FDG PET / CT上显示多发性高代谢性结核病灶，其中一名患者有恶性病史。本病例报告的目的是强调在解释FDG PET / CT时需要使用其他的结核病鉴别诊断技术，特别是在结核病流行国家。仅通过分析诊断成像，极有可能将无症状结核病患者误解为具有恶性肿瘤。因此，
