This was followed up with a PET scan that showed high FDG uptake in lymph nodes in the neck (SUVmax 7.7), mediastinum (SUVmax 44.7), and pulmonary hila (SUVmax 30.9 on right and 24.0 on left), suggestive of lymphoma (Figure 1, Figure 2).

52-year-old female with sardoidosis. Axial FDG-PET image of the chest done three months after starting treatment for sarcoidosis. This image shows interval decrease in activity of hypermetabolic lymph nodes throughout the mediastinum and bilateral pulmonary hilar regions, suggesting a positive therapeutic response.
