[Show abstract][Hide abstract] ABSTRACT: In a 70-year-old female with history of left breast cancer (S/P mastectomy 21 years ago) and gastric lymphoma (S/P partial gastrectomy six years ago), a new apical lesion in the left lung was revealed by recent thorax CT. FDG PET/CT study was requested to evaluate the thoracic mass and extent of the disease. FDG PET showed three foci of intensely increased FDG uptake in the left lung, mediastinum and right groin (not shown). All these pathologic findings correlated with CT lesions (not shown). Coronal and transaxial whole body FDG PET images (Figure 1. D, E, F) demonstrates multiple hypermetabolic foci at the iliac bifurcation level corresponding mass lesion on CT images.
