We report the case of a 64-year-old man who presented with back pain, anorexia, and weight loss 9 months following bacillus Calmette-Guérin immunotherapy for high-grade transitional cell carcinoma of the bladder. A FDG PET/CT was performed, which demonstrated osteolysis and intense FDG avidity of the T6/T7 and T8/T9 vertebral endplates. In addition, an aneurysm with FDG-avid soft tissue was present of the distal left common iliac artery. The provisional diagnosis was disseminated bacillus Calmette-Guérin infection, resulting in spondylodiscitis and a mycotic aneurysm. A CT-guided vertebral biopsy confirmed the presence of Mycobacterium tuberculosis DNA on polymerase chain reaction testing.
我们报告了一例 64 岁男性病例，他在因高级别移行细胞膀胱癌接受卡介苗免疫治疗 9 个月后出现背痛、食欲不振和体重减轻。进行了 FDG PET/CT 检查，显示 T6/T7 和 T8/T9 椎体终板的溶骨性病变和强烈的 FDG 摄取。此外，左侧髂总动脉远端还存在一个伴有 FDG 摄取的软组织的动脉瘤。初步诊断为播散性卡介苗感染，导致脊椎炎和真菌性动脉瘤。CT 引导下的脊柱活检通过聚合酶链反应检测证实存在结核分枝杆菌 DNA。
