Abstract

An 86-year-old man presented with slurred speech and right lower limb shaking for 1 month. Initial brain MRI revealed an abnormal signal lesion in the left parietal lobe with peripheral parenchymal edema, and brain metastases were suspected. Subsequent PET/CT showed increased focal FDG uptake in the left parietal lobe, accompanied by bands of surrounding brain parenchyma edema. No other abnormal lesions were observed on 18 F-FDG PET/CT except for increased inflammatory lymph node activity in the left hilar region. Finally, the cerebrospinal fluid puncture culture showed a Micrococcus luteus infection. Therefore, the clinical diagnosis was infectious lesions.

颅内黄体微球菌感染在18F-FDG PET/CT上模拟脑转移。

86岁男性，以言语不清、右下肢颤抖1个月为表现。最初的脑部MRI显示左顶叶异常信号病变伴周围实质水肿，怀疑脑转移。随后的PET/CT显示左顶叶局灶性氟脱氧葡萄糖摄取增加，并伴有周围脑实质水肿。18F-FDG PET/CT除左肺门区炎性淋巴结活动性增高外，未见其他异常病变。脑脊液穿刺培养为黄体微球菌感染。因此，临床诊断为感染性病变。
