The small bowel is an uncommon site for cancer metastasis. Despite this, cases have reported the duodenum as a metastatic site from local organs. However, duodenal involvement from more distant organs, such as the ovaries, has rarely been reported. Herein, we present a case of a 68-year-old female who developed duodenal metastatic disease from a primary ovarian serous adenocarcinoma. The goal of this report is to encourage clinicians to keep a broad differential in patients complaining of abdominal pain, especially in those with a history of primary ovarian malignancy.

不太可能的途径：十二指肠内转移性卵巢恶性肿瘤。

小肠是癌症转移的罕见部位。尽管如此，仍有病例报告十二指肠是局部器官的转移部位。然而，来自较远器官（例如卵巢）的十二指肠受累的报道很少。在此，我们介绍一名 68 岁女性的病例，她因原发性卵巢浆液性腺癌发展为十二指肠转移性疾病。本报告的目的是鼓励临床医生对主诉腹痛的患者，特别是有原发性卵巢恶性肿瘤病史的患者进行广泛的鉴别。
