Breast incidentaloma: Cardiac PET readers beware.

Breast cancer remains one of the most common causes of cancer and cancer-related death in women. With increases in medical imaging utilization, incidentally detected cancer has become more prevalent. Specifically, breast cancer can be incidentally detected on nuclear cardiac imaging scans due to its high metabolic activity and because the tumor may fall within the field of view during these studies. We report a unique case of ductal carcinoma in situ found on Nitrogen-13 ammonia myocardial perfusion positron emission tomography-computed tomography (PET-CT) in a patient undergoing work up for chest pain.
