Figure 1: Maximum intensity projection image (a) of staging ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography showing fluorodeoxyglucose-avid mediastinal mass and lymph nodes. Axial and coronal fused positron emission tomography/computed tomography images (b and d) showing fluorodeoxyglucose-avid mediastinal mass lesion and lymph nodes. Maximum intensity projection image (e) of interim ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography scan. Axial and coronal fused positron emission tomography/computed tomography images (f and h) showing mildly fluorodeoxyglucose-avid mediastinal mass. Axial and coronal fused positron emission tomography/computed tomography images (g and h) showing new focal fluorodeoxyglucose-avid lesion in the inferior pole of spleen which was not seen on previous scan (c)
