Visualization of cardiac metastasis from medullary thyroid carcinoma on F-18 DOPA PET/CT scan.

Cardiac metastases are frequent (10%-12%) at autopsy of patients who have died of advanced cancers, but are usually clinically unrecognized. Melanoma, lymphoma, lung, and breast cancers are the main tumors inducing cardiac metastases. We present a case of cardiac metastasis which accumulated F-18 fluorodeoxyglucose and F-18 fluorodihydroxyphenylalanine in a 56-year-old woman with recurrent medullary thyroid carcinoma.
