摘要
患者女,51岁,主诉体检发现盆腔肿物3个月,出现下腹胀伴压痛3周。患者3个月前外院体检超声提示宫底前壁肌间多个偏低回声团,血流信号丰富,最大者8.2 cm×7.1 cm,内膜厚约1.3 cm,宫腔内未见明确异常。盆腔增强MRI提示右侧附件区多发团块状异常信号,考虑卵巢来源,不除外恶性病变可能。同期查肿瘤标志物糖类抗原(carbohydrate antigen, CA)125、CA19-9、癌胚抗原、人附睾蛋白4均正常。3周前患者无明显诱因出现下腹胀伴压痛。为明确盆腔病变性质,患者行
18F-FDG PET/CT显像(图1)。PET/CT可见子宫右后方不规则实性肿物,密度均匀,大小约8.5 cm×6.0 cm,肿物与邻近子宫后壁分界不清,SUV
max 4.4;子宫右旁亦见一不规则实性肿物,大小约6.7 cm×4.9 cm,SUV
max 3.6;子宫腔内见条片状代谢增高影,SUV
max 8.6,考虑为子宫内膜生理性摄取;盆腔少许积液;甲状腺左叶另见一代谢增高的结节,SUV
max 41.9,考虑为甲状腺原发病变,建议患者进一步行超声检查明确甲状腺结节性质。
