A 55 year hypertensive man presented with shortness of breath, productive cough and loss of weight. To rule out underlying malignancy, he underwent F-18 FDG PET/CT which showed bronchiectatic changes and tree-in bud nodules in bilateral lung fields with no definitive of evidence of metabolically active disease to suggest malignancy. There was no organomegaly and pulmonary to aorta ratio was also normal (0.73). However, diffuse FDG uptake was seen in the right ventricle which is uncommon due to less muscular mass in comparison to the left ventricle. The serum NT- pro BNP was raised to 265 pg/ml (upper limit less than 125 pg/ml) confirming heart failure.
