Figure 1.

Posttreatment positron emission tomography (PET)–computed tomography (CT) in a 60-year-old man. (a) Axial CT scan at the level of the left atrium shows crescent-shaped soft tissue masses in both subscapular lesions deep to the latissimus dorsi muscles, with the right bigger than the left (white arrows). (b) Axial nonattenuation corrected PET image shows tracer uptake in the bilateral posterolateral chest (black arrows). (c) The fused PET-CT image, in which the area of hypermetabolic activity corresponds to the soft tissue masses (white arrows), shows an SUV max of 2.7 in the right mass and 2.1 in the left.
