Abstract
Noncardiac abnormalities are not uncommon in myocardial perfusion imaging. With the advent of SPECT/CT hybrid system, CT could produce high-quality attenuation maps to improve resolution. In addition, extracardiac abnormalities are easily differentiated by using SPECT/CT. We report a 47-year-old man who felt chest tightness on exertion for 2 months. He denied hypertension, diabetes mellitus, or hyperlipidemia. Dipyridamole stress and redistribution myocardial SPECT revealed no perfusion defect. However, a retrocardiac mass with focal radioactivity was identified in the projection images, corresponding to a kidney shadow in the low-dose noncontrast CT scan. Subsequent conventional CT scan confirmed the diagnosis of thoracic renal ectopia. ? 2009 Lippincott Williams & Wilkins.
