Abstract

18F-fluorodeoxyglucose positron emission/computed tomography (18F-FDG PET/CT) imaging, an established procedure for evaluation of malignancy, shows an increased 18F-FDG uptake in inflammatory conditions. We present three patients with abdominal pain and weight loss. Conventional imaging studies indicated that abdominal neoplasm and 18F-FDG PET/CT for assessment of malignancy showed multiple lesions with intense 18F-FDG uptake in abdomen of the three cases. However, the three patients were finally diagnosed with multi-site abdominal tuberculosis (TB). Of them, two were diagnosed with TB by pathology, one was diagnosed with TB clinically. They recovered after anti-TB therapy. Few reports on accumulation of 18F-FDG in abdominal TB are available in the literature. A high index of suspicion is necessary to achieve an early diagnosis and a better outcome of the disease.

摘要

18F-氟代脱氧葡萄糖正电子发射/计算机断层扫描(18F-FDG PET/CT)成像,一种用于评估恶性肿瘤的既定程序,显示炎症情况下 18F-FDG 摄取增加。我们介绍了 3 例腹痛和体重减轻的患者。常规影像学检查提示腹部肿瘤,18F-FDG PET/CT 评估恶性肿瘤显示 3 例患者腹部有多个病灶,18F-FDG 摄取明显增加。然而,这 3 名患者最终被诊断为多部位腹部结核(TB)。其中,2 例经病理诊断为 TB,1 例临床诊断为 TB。他们在接受抗结核治疗后康复。文献中很少有关于腹部 TB 中 18F-FDG 积聚的报道。需要高度怀疑才能实现早期诊断和更好的疾病结局。
