Figure 1

Representative images in a patient who was treated with surgery and radiotherapy for thymoma. Restaging FDG PET/CT showed increased uptake at the right pleura nodule (a–d, arrows; SUVmax, 4.3). In addition, several small-size nodules on the right pleura with negative FDG uptake were also observed on PET/CT (e–g, arrows). The pleural lesions were then surgically resected and confirmed by histopathology as recurrences of thymoma.
