Focal Nodular Hyperplasia of the Liver Detected on Myocardial Perfusion PET/CT.

A 65-year-old woman with a few episodes of chest pain and progressive dyspnea on exertion was sent to the department of nuclear medicine for myocardial PET/CT. Pharmacological stress was performed with adenosine. During pharmacological stress, neither anginal complaints nor changes in electrocardiogram were observed. The PET/CT showed normal tracer uptake in the myocardium with normal myocardial flow and normal flow reserve. Furthermore, normal wall motion and left ventricle ejection fraction of 74% were observed. Incidentally, four 13N-NH3-avid liver lesions were detected. An additional MRI of the liver showed that these lesions were typical for focal nodular hyperplasia.
