External beam radiation therapy successfully reduced the metabolic activity of anaplastic thyroid carcinoma metastases in the right atrium and ventricle without causing pacemaker dysfunction.
Case Report (n=1)
Anaplastic thyroid carcinoma (ATC) is a rare, aggressive malignancy, which is known to metastasize to the heart. We report a case of a patient with ATC with metastatic involvement of the pacemaker leads within the right atrium and right ventricle. The patient survived external beam radiation treatment to his heart, with a radiographic response to treatment. Cardiac metastases are usually reported on autopsy; to our knowledge, this is the first report of the successful treatment of cardiac metastases encasing the leads of a pacemaker, and of cardiac metastases from ATCs, with a review of the pertinent literature.
Dasgupta et al. (Mon,) conducted a case report in Anaplastic thyroid carcinoma metastatic to the right cardiac atrium and ventricle (n=1). External beam radiation therapy (IMRT) was evaluated on Radiographic response. External beam radiation therapy successfully reduced the metabolic activity of anaplastic thyroid carcinoma metastases in the right atrium and ventricle without causing pacemaker dysfunction.
