Liver radiotracer activity interfering with the inferior myocardial wall in a patient undergoing myocardial perfusion imaging (MPI) with 99mTc-Sestamibi is a known pitfall. We report a patient with pituitary macroadenoma who was subjected to stress-MPI study for pre-anesthetic clearance. The post-stress raw image showed the liver radiotracer activity in close approximation to the anteroseptal wall of the left ventricular myocardium, secondary to right hemi-diaphragmatic eventration.
