AN INCIDENTALLY DETECTED CASE OF ATYPICAL BRONCHIAL CARCINOID IN STRESS MYOCARDIAL PERFUSION SPECT/CT

Abstract

Myocardial perfusion imaging (MPI) is primarily done to look for stress induced perfusion defects in patients suspected of coronary artery disease. However, the rotating raw images can provide a significant information regarding surrounding structures. The lungs lie in close proximity to heart and any abnormality showing increased uptake can be seen on MPI. We report a case of 52-year-old man, with history of diabates for last 5 years, who presented to cardiac outpatient department (OPD) for occasional chest pain and dyspnea. Electrocardiogram (ECG) and echocardiography showed no significant abnormality. Patient was referred to nuclear medicine department for stress induced myocardial perfusion scintigraphy. The raw 99m-Tc sestamibi images were showing abnormal uptake in right lung hilar region which on subsequent investigations was diagnosed as a case of atypical bronchial carcinoid tumor.
