Breast cancer is the most common malignancy among women across the globe. Despite receiving treatment, patients may develop recurrence and metastasis. Breast cancer most commonly metastasizes to the bones, lungs, liver, lymph nodes, and brain structures. Metastasis to the gastrointestinal tract is rare, with only a few cases reported in the literature. F18-fluorodeoxyglucose positron emission tomography-computed tomography is performed to localize occult metastasis and suspected recurrence of breast carcinoma that remain undetected in conventional imaging techniques despite rising tumor markers. This case report describes an unusual course of the disease in a patient treated for breast cancer with late presenting colon metastasis mimicking primary colon cancer on fluorodeoxyglucose positron emission tomography-computed tomography. This case demonstrates that fluorodeoxyglucose positron emission tomography-computed tomography can identify the occult metastatic site in patients with breast cancer even at a rare site such as the colon; however, histological evaluation is required to differentiate between breast cancer metastasis to the colon and primary gastrointestinal malignancy.
