Abnormal 18F-FDG Uptake Detected with Positron Emission Tomography in a Patient with Breast Cancer: A Case of Sarcoidosis and Review of the Literature

Figure 1

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.
