[18F]FDG and [18F]FES PET/CT images of a 46-year-old female with lobular carcinoma and histologically confirmed ER-positive recurrence in the left axillary level II lymph node (Allred score = 8). Maximum intensity projection (a) and transaxial [18F]FDG images (b–e) show equivocal uptake in the left axillary lymph node (arrows) and physiologic bone uptake in the thoracic spine (dotted arrows). However, positive [18F]FES uptake is seen in the axillary lymph nodes (f–h; arrows) and the first thoracic vertebra (f, i, j; dotted arrows)
