18-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) revealed high FDG uptake in the left chest wall mass without any other uptake (Fig. 4A and B), so we diagnosed her with primary malignant lymphoma originating from the chest wall. Chest CT performed four months later showed complete response (Fig. 4C and D).
