Abstract An increased number of patients with cancer who are receiving methotrexate for autoimmune conditions or immune checkpoint inhibitor (ICI) myocarditis are presenting to the radiation oncology department. In this article, we report a case of a patient with ICI myocarditis on methotrexate who received radiation to the chest wall and nodes. In this case, methotrexate did not increase the risk of severe acute toxicities of radiation.
