Metastases to gastrointestinal tract from breast cancer are very rare and can be diagnostically challenging. In this case, we reported 18 F-FDG and 68 Ga-FAPI PET/CT findings in a 54-year-old women with such uncommon metastases from breast cancer. Although the primary tumor of breast cancer remained radiologically occult, 68 Ga-FAPI PET/CT showed a far better tumor-to-background ratio than 18 F-FDG PET/CT for detecting the metastatic lesions, especially for detecting the retroperitoneal lymph node and rectal metastases.
乳腺癌胃肠道转移非常罕见，诊断具有挑战性。本病例报告了一例 54 岁女性罕见的乳腺癌胃肠道转移，18 F-FDG 和 68 Ga-FAPI PET/CT 的检查结果。虽然乳腺癌原发灶在影像学上仍隐匿不显，但 68 Ga-FAPI PET/CT 比 18 F-FDG PET/CT 显示出更好的肿瘤与背景比，更有利于检测转移病灶，尤其是腹膜后淋巴结和直肠转移灶。
