Abstract

We report an unusual case of uterine corpus metastasis from rectal adenocarcinoma detected using F-FDG PET/CT. A 47-year-old woman was diagnosed with rectal adenocarcinoma and treated with surgery and radiochemotherapy 3 years ago. During follow-up, she presented with lower abdomen pain and elevated tumor markers, but ultrasonography findings were unremarkable. We performed an F-FDG PET/CT scan, which showed intense F-FDG avidity in the myometrium of the uterine corpus. Uterine corpus metastasis was suspected, and complementary MRI and diagnostic curettage histopathology confirmed uterine metastasis from rectal adenocarcinoma.

摘要

我们报告了一例使用 F-FDG PET/CT 检测到的直肠腺癌子宫体转移的不寻常病例。一名 47 岁女性被诊断为直肠腺癌，3 年前接受了手术和放化疗。在随访期间，她出现了下腹疼痛和肿瘤标志物升高，但超声检查结果无明显异常。我们进行了 F-FDG PET/CT 扫描，显示子宫体的子宫肌层有强烈的 F-FDG 摄取。怀疑为子宫体转移，补充的 MRI 和诊断性刮宫组织病理学证实了直肠腺癌的子宫转移。
