FIGURE 2. Results for patient 5, a 32-y-old man with a B-cell diffuse large lymphoma. (A) A baseline 18F-FDG PET image revealed increased activity throughout the right nasal cavity and mediastinal nodes. (B) At day 1, abnormal uptake in the nasal cavity was visually identical to that at baseline, but uptake in the mediastinum was decreased. (C) At day 20, the 18F-FDG image was basically normal, with slightly abnormal uptake in the nasal cavity or mediastinal nodes. (D) At the end of chemotherapy, uptake in the mediastinal nodes reappeared, but uptake in the nasal cavity remained normal.
