Coronal FDG-PET images showed a focus of mildly increased FDG activity (SUV max = 2, 1) in the medial segment of the upper lobe in the left lung (dotted arrows) and multiple moderate to markedly increased FDG foci (SUV max = 3, 4) in the right-sided axillary lymph nodes (arrows) in a 63-year-old woman, who underwent FDG-PET scan for the evaluation of enlarged right axillary lymph nodes and lung nodules, for the detection of recurrent metastatic breast cancer disease. Histopathologic examination of the axillary and endobronchial lesions revealed sarcoidosis.

FDG PET revealed abnormal FDG accumulation in the left lung with mild metabolic activity (SUV max: 2.1), and also moderately high metabolic activity (SUV max: 3.4) related to multiple lymph nodes in the right axilla (Figure 1). Finally, the patient was convinced for an excisional biopsy from axillary lymph node as well as endobronchial lymph node biopsy, which were revealed sarcoidosis.
