Serendipitous Discovery of Non–Sestamibi-Avid Squamous Cell Lung Cancer Invading the Heart During Myocardial Perfusion Imaging

Abstract

Scintigraphic and radiographic correlation of a non-sestamibi-avid lung mass invading the left ventricle serendipitously discovered during adenosine myocardial perfusion imaging is presented. The only clue to the presence of the mass was deformation of the anterior wall on SPECT myocardial perfusion imaging. This case serves as a reminder that although the appearance of pathology on a nuclear medicine imaging study is typically what is seen (specifically, increased radiopharmaceutical uptake), it can just as importantly be what is not seen.
