The most common sites of distant metastases are lung, bone, pleura, and mediastinum in malignant phyllodes breast tumors. However, small bowel metastasis from malignant phyllodes breast tumors is rare. We reported that using CT and FDG PET/CT imaging we identified a case with small bowel metastasis from breast cancer. PET/CT scan showed that high 18 F-FDG uptake occurred in the duodenum and jejunum. Histopathology and immunohistochemistry analyses further confirmed that malignant phyllodes tumors are derived from the breast.
恶性叶状乳腺肿瘤最常见的远处转移部位是肺、骨、胸膜和纵隔。然而，恶性叶状乳腺肿瘤的小肠转移较为罕见。我们报告了一例使用 CT 和 FDG PET/CT 成像识别的乳腺癌小肠转移病例。PET/CT 扫描显示十二指肠和空肠存在高 18 F-FDG 摄取。组织病理学和免疫组织化学分析进一步证实恶性叶状肿瘤来源于乳腺。
