a Axial PET/CT image demonstrates a focal area of avid FDG uptake in the right true vocal cord (arrow) suspicious for a tumour lesion. b Corresponding non-contrast axial CT image shows no definite focal lesion in the right vocal cord. CT images at other levels of the larynx were normal. Clinical history mentioned recently diagnosed left vocal cord paralysis confirmed by fibre optic endoscopy. This compensatory increased uptake in the right vocal cord was due to recent left vocal cord paralysis. This case illustrates the need for rigorous correlation with clinical findings whenever the only abnormality observed is unilateral vocal cord FDG uptake
