Solitary lung metastases more than 10 years after the resection of endometrial carcinoma are a rare occurrence. However, no cases have undergone stereotactic ablative radiotherapy (SABR) for solitary lung metastasis that developed more than 10 years after resection. A 76-year-old woman with a history of endometrial carcinoma 13 years prior was diagnosed with a lung tumor that was confirmed to be a metastasis from the endometrial carcinoma. Due to other health issues, the patient was not eligible for surgery and instead underwent SABR. The treatment was well-tolerated and no adverse events were reported during or up to 2 years after SABR. SABR may be considered as a safe and effective treatment option for lung metastases of endometrial carcinoma that develop more than 10 years after the initial treatment.
